A completely lost episode, we have a voice-narrated reconstruction.

Episode 1:

 The TARDIS materialises above the ocean, slowly lowering to the water. The Doctor and his companions exit the TARDIS in an inflatable boat and make it to shore. They postulate that they’re in England, and Victoria asks if they always go to Earth (which makes no sense, as she’s been off-planet already), and Jamie remarks that it’s always England.

 The Doctor and his companions play on the beach, throwing foam at each other. In the midst of the shenanigans, Jamie sees something down the beach and they head down the shore to investigate. A giant steel pipe comes up out of the sand, curving into the cliffside. The pipe is marked Euro Sea Gas.

 The Doctor investigates the large black box but cannot seem to open it. He pulls out of his pocket a small OH MY GOD IT’S THE SONIC SCREWDRIVER – IT’S THE VERY FIRST APPEARANCE OF IT! OH HOLY COW, HOLY SHIT! SQUEEEEEEEEE!!!!

 Ahem. Anyhow, so he opens the lid of the box with the sonic screwdriver. As he pokes around, there’s a rumbling. He closes the lid and listens to the pipe using a stethoscope. Victoria says she feels they’re being watched. Well, that’s not true. She WHINES that she feels they’re being watched.

 Which they are. We see a monitor with an image of The Doctor and crosshairs which center on him.

 There’s a shot and The Doctor crumples to the sand. The companions rush to his side and each of them are shot by the weapon as well.

 Victoria awakens, to find herself indoors, laying on the floor. Two guards stand over her, as well as Jamie and The Doctor. All three are laying on the floor near each other. They waken, but they cannot move their arms or legs. They ask questions but nobody in the room – the guards or a group of men nearby – answer until another man, obviously in some position of authority enters, demanding to know who they are.

 The travelers are given something to facilitate their recovery and are soon standing. The man accuses them of being sabouteurs. He orders the three strangers to be locked away in a cabin to be interrogated later. One of the technicians explain that they’ve lost touch with one of the rigs at sea and everyone is tense because of that. Also, due to the loss of pressure in the lines and the fact that they were in a restricted area and The Doctor was tampering with the release valve, the connection isn’t a hard one to make.

 As they taking away to be locked up, a warning flight flashes on one of the consoles in the room.

 While being questioned about what he was doing, The Doctor says that he heard something moving in the tube, not messing around with the pressure valve.

 In the console room, contact has been reestablished with the rig, but the signal is not strong and the man on the monitor is being very strange – he’s whispering/mumbling and keeps repeating himself and there’s horrible feedback.

 Harris, the second in charge, goes to Robson (his boss) to suggest listening to The Doctor and shutting down the flow and checking the pipe out. Robson won’t hear of it, even when another technician informs them that pressure is down another 3 levels – it’s dropping 3% every 20 minutes.

 While they argue, someone grabs some papers out of a briefcase. Harris finally gets Robson to agree to look at his file, and Harris goes to retrieve his file from the briefcase, but it’s the file that was swiped! Harris runs into his wife, Maggie, and sends her to their quarters to fetch the file, which he has assumed he left there instead of putting it in his briefcase.

 The Doctor and his companions slip out of their locked cabin.

 Maggie finds the file, but not where it was supposed to be. Inside the file is seaweed, which stings her. She throws it out… and it begins to bubble and writhe.

 Robson argues with Van Lutyens, a representative from the Dutch government, over Robson’s handling of morale. The Doctor and companions overhear the agument.

 Robson receives a communication from one of the rigs, and the man says that something has gotten into the pipeline.

 Victoria is sent by The Doctor back to the cabin, but she ends up going off on her own, poking about.

 Maggie is suffering ill effects from the seaweed sting. Harris gets permisison to check on his wife.

 We see someone with white gloves (the same as the peson who took the file from Harris’ briefcase) and a gas mask tampering with oxygen supplies, bleeding out the resevoirs. They stop when they hear someone outside.

 Victoria moves down a corridor and slips into a room to evade Harris who is coming down the hall. She’s slipped into the very same store room. The thick amount of oxygen in the room is stifling. The person in the gas mask pushes past her and locks her in. Outside the saboteur activates the ventilation in the room and moves away.

 Jamie and The Doctor poke about, finding a large room with a great number of pipes and valves and gauges. There’s an observation deck where the technicians can observe the contents of the pipeline, as that part of the pipe is transparent.

 Foam bursts through the ventilation into the room with Victoria… and there’s something moving in it.

 The Doctor and Jamie hear the burbling noise in the pipes again. Then, Victoria’s screams, calling their names. Her voice echoes through the pipes and the various rooms throughout the compound. The seething foam continues into the room with Victoria. There’s tendrils of seaweed that seem to be animate, reaching out for her and she screams… and the credits roll.

 No idea what’s going on, but something is. This whole season, except for The Enemy of the World, seems to be about locations under seige – the monastery, the underground station, the science station, even the tomb of the Cybermen – and this one already seems to fit that bill.

 All in all, a decent story. There’s a handful of points that are a bit silly/sloppy, writing wise, but by no means is it a bad one. Most of the characters are done well enough. You’ll have to read on to find out about the cast member who has a connection to the new Doctor Who run… and find out what drastic change happens to the TARDIS crew.

Episode 2:

 They find Victoria and get her out of the room. Robson and Van Lutyens show up, the former demanding to know who let them out of the cabin. Victoria says there was some creature in the foam and it came after her and she breaks into hysterics.

 An engineer discovers that the oxygen tanks have been bled empty. Robson accuses Victoria of sabotage but they quickly show that she couldn’t have locked herself in from inside.

 Harris checks on his wife; Maggie seems very out of sorts (much like the man who communicated from the lost rig), very confused. She’s having trouble recalling what happened. They hear a noise at the patio and they peek, seeing the seaweed she through out there, covered in foam and burbling and popping. This freaks Maggie out immensely. Harris leaves to find a doctor. Maggie lays down, staring at the ceiling, listening to the pounding in her head. She enters a trance-like state and walks to the patio door. She opens the door but manages the will to slam it shut, which seems to break her free of whatever was controlling her.

 The Doctor tells Lutyens and Robson that he heard a thumping sound in the pipe room. Lutyens says that was a noise heard out on the rigs, but Robson tries to play it off as a “mechanical fault”. Again, Robson refuses to turn off the gas flow.

 Jamie and Victoria learn from a technician about the rigs out at sea. Apparently the rigs pump gas to a central rig which sends it to the facility.

 Harris arrives and asks The Doctor for assistance with Maggie. Robson tells him that his domestic affairs have no place in the facility. After Harris threatens him, Robson gives The Doctor one hour to check on Maggie.

 Someone buzzes the door at the Harris residence. Maggie answers to find two (as the narrator says) almost comical men – one gaunt and tall, the other short and more squat of build. They introduce themselves as maintenance controllers and ask to speak to her husband. Maggie explains he’s away and they tell her they’re here to carry out an inspection, one that needs to be carried out without delay. Maggie allows them in.

 The short, fat man is Mister Oak, the gaunt man is Mister Quill. They assure her that they won’t be long, she won’t even know they’re there.

 A technician tells Lutyens that there’s a pressure build up as well as pressure loss and it’s just a matter of time before, as Ivanova from B5 would says, “Boom”. Robson orders for gas to be released through a pressure valve – apparently anything to avoid shutting off the gas.

 Maggie has returned to her bedroom, while the two men inspect something in the kitchen. Mister Oak has tendrils of seaweed inside the sleeves of his coveralls. They both don white gloves, presumably like the ones we’ve seen on the hands of the thief and the saboteur. They open the patio door. They give each other delighted glances as the foam moves into the house.

 Maggie is brushing her hair at her dresser when the two men enter. She asks what they want but they do not reply. Instead they open their mouths and breathe out something that makes Maggie choke and gasp and collapse.

 On the beach, we see an outlet valve burning off the excess gas. The technician reports that the pressure has returned to normal – seems that Robson was right that the pressure could be bled off in time to avoid an explosion.

 Robson and Van Lutyens argue more. Price, another technician, says that he cannot raise C Rig.

 Harris brings The Doctor and his companions to his home. Victoria recognises the gas smell from when she was trapped in the oxygen room with the foam and they smash a window to air out the house and find Maggie’s unconscious form.

 Price still cannot raise the C Rig. Van Lutyens continues to argue with Robson who says Harris’ figures are bunk. We have another classic megalomaniac here, I think. Robson says that Van Lutyens is an advisor, but he has no obligation to follow any advice.

 The impeller machinery slows down and Van Lutyens demands Robson for answers, but the man has none. There’s a thumping, almost heart-beat like sound coming from the machinery.

 Maggie is in a coma. They find seaweed on the floor in the house. Harris realises that the seaweed was meant for him.

 Van Lutyens gets frustrated with the Chief Engineer’s reluctance to go against Robson’s opinion. Van Lutyens is continually frustrated that Robson has such a choke hold on everything. Robson comes in and they argue some more. Van Lutyens says that something is alive down there, in the darkness, waiting… and the credits roll.

Episode 3:

 In the TARDIS, The Doctor experiments with the seaweed sample. His companions are assisting him. They confirm that the seaweed is definitely animate.

 Van Lutyens tries to talk to Harris but he is too preoccupied with his wife’s condition. He checks again with Price to see if facility’s doctor has returned from the rig (think it’s D Rig, which is the one they had lost communication with prior to the start of the show but recently talked to the strangely behaving superior there), but he has not. Robson asks him what’s the emergency now, all smart ass like, suggesting that she has a hangover.

 Robson blames Harris for leaving The Doctor and his companions behind, and goes off on a rant that The Doctor is a saboteur, responsible for everything that’s going wrong. (Okay, I know megalomaniacs and people stupidly loyal to one thought make for great heels, especially back in the 60s, but this one is a bit too one-trick pony for my taste.) He’s more worried about his reputation than safety or anything else.

 The Doctor pulls out a reference book and shows Victoria a picture of a creature – a book of legends of superstitions; that particular page is a creature from the mariners of Jamie’s time. As they’ve been talking, the seaweed has been growing bigger and giving off gas. They narrowly manage to get the seaweed contained.

 Van Lutyens is now being accused by Robson for leading everyone against him. He even blames the Chief Engineer for turning against him. He’s screaming that he’s in charge, he has the responsibility and storms out. Van Lutyens puts in a call to the Dutch government, hoping they can pressure London to remove Robson.

 Robson returns to his quarters, but cannot rest, he’s too wound up. Outside his corridor, we see Mister Oak approaching Robson’s door, and locks the door with a key. Robson calls out that he’s not to be disturbed. Oak operates the ventillation, and Robson sees the foam, filled with tendrils of seaweed, snaking towards him.

 Harris arrives, opening Robson’s cabin door, who bursts out, running. Harris sees what’s inside and runs out himself.

 The Doctor, Victoria and Jamie return to the Harris quarters, but find a large mass of seaweed and foam there. It moves towards Victoria, who screams, and the mass seems to stop and depart. Jamie is trapped in the kitchen and The Doctor and Victoria go above and help him out through the skylight onto the roof. The foam follows out after them and they run.

 Van Lutyens and Harris return to Robson’s cabin, but the creature is gone, only bits of foam remain to indicate it was ever there. Van Lutyens advises Harris to put out a security alert for Robson – he might be ill. He puts out the order for all ventilation grills to be kept closed.

 (It’s funny, but Harris reminds me of Andrew McCarthy a bit.)

 Van Lutyens pushes Harris to assert control, but he refuses to officially usurp Robson’s position. He’s willing to issue orders and make judgment calls, but that’s it. He does contact London, especially after Van Lutyens says that he’s already informed his superiors in The Hague.

 As they return from the Harris quarters, Jamie has to rest. Victoria asks The Doctor why they always end up facing trouble, and we see a series of flashbacks from Evil of the Daleks, where we first met Victoria, to Tomb of the Cybermen (where Kaftan had her at gun point), then in The Abominable Snowmen, where Padma was controlling Victoria, and other sequences, all focusing on Victoria being in trouble, facing danger or fearsome creatures. I guess this sequence is to show us that Victoria is still extremely self-centered? (I do believe it’s a contrivance of the reconstruction, though it’s well presented.) When The Doctor asks her what’s troubling her, she says, “I wish… oh, never mind.”

 Harris has placed the call, informing them that he’s taken over. He’s learned that, in three hours, his superiors will be there. The Doctor (and his companions) arrive and he tells them that their enemy is seaweed that has become sentient and animate.

 Pride reports that Maggie has not been collected by the medical center and The Doctor tells Harris that they were just at his cabin and there was no sign of her, only the seaweed.

 Maggie is on the beach, her neck and face covered in seaweed. Robson arrives, glassy-eyed. She tells him, “you know what to do. You will obey.” Robson agrees, and watches as Maggie walks out into the sea, engulfed by the waves… and the credits roll.

Episode 4:

 There are three rigs now they cannot contact, with the additon of Rig A. The thumping in the impeller has started again.

 In the bunk room, Jamie is sleeping but Victoria is restless, so she wakes him up so she can bother him with her worrying. Victoria seems very burnt out on their lifestyle, the wandering, the danger… but every time Jamie tries to talk to her about it, she blows it off.

 I really wanted to like Victoria, but she’s ended up just as whiny as Susan and Vicki were. The Doctor returns and checks in on Jamie. He’s glad to hear that. Victoria starts fretting again, complaining that wherever they go, there’s something awful. She asks why they can’t go somewhere pleasant, peaceful.

 Harris is searching for his wife, but finds Robson on the beach, staring out at sea. Robson tells Harris that he’ll find his wife very soon and turns and walks away from the confused Harris.

 The Doctor warns Van Lutyens about sending anyone down the impeller. Van Lutyens is going himself, as he doesn’t have the authority to ask anyone else to go down. The Chief Engineer gives the order to lower the platform after Van Lutyens enters, and we see Oak and Quill are the men operating the platform controls.

 He’s lowered down and puts on his gas mask and pulls out a torch (flashlight). He peers into a chamber below a hatch. He hears the all too familiar heart beat sound and within the chamber is the foamy seaweed mass, which surges up and grabs him and pulls him in.

 Above, everyone is worried. The platform is brought back up, but there’s nobody there. The Doctor insists on going down, guilting Jamie into going along while Victoria whines.

 Price informs Harris that the director, Megan Jones, is on her way from London. Harris comes to the impeller shaft and learns that Van Lutyens has gone down and disappeared and Jamie and The Doctor have gone down to investigate what happened to him.

 Megan Jones (who is played by Margaret John, an accomplished actress, who also appeared in a new Doctor Who story as Grandma Connolly in “The Idiot’s Lantern”), the director of Euro Sea Gas, has arrived at the facility. Harris has to go meet her and he leaves orders with Oak and Quill to bring them up as soon as they signal.

 Jones doesn’t find Harris’ claims all that credible. When Harris asserts that he’s seen the creatures, she implies that he’s under a lot of stress and with his wife being ill, perhaps he’s seeing things. She tells him to send the helicopter to inspect the rigs. When she says she wants to speak to Robson, Harris says Robson is ill but cannot give her any specifics.

 Down in the pipe chamber, The Doctor and Jamie run from the foamy seaweed mass. Jamie hits the recall button but nobody is above to bring them up.

 Price tries to contact Rig D again, to no avail. The Chief Engineer asserts Harris’ claim that whatever is interfering with the impeller is down the shaft, nothing is wrong with the impeller in the facility.

 The Doctor and Jamie find a maintenance ladder and begin to climb it.

 Oak and Quill return from an adjoining room, still ignoring the recall signal, and depart, locking the door. 

 Jamie and The Doctor have made it up the shaft. They exit and wonder where everyone is, especially Victoria.

 The helicopter has already reported back (the timing here seems a bit wonky – I would think it would take a sole helicopter some time to fly by all the rigs) that the rigs are covered with foam and seaweed. Harris asks for permission to evacuate the rigs and blow them. Jones’ assistant scoffs at his idea, and even Megan Jones finds it a bit preposterous – she’s thinking of the years and the investment in the rigs, of course.

 Robson shows up, screaming for them to leave the rigs alone, they are his rigs. He’s visibly mad, saying “we won’t allow it”, and staggering about confusedly. The Doctor shows up to report that the bottom of the impeller shaft is covered in weed and foam. He says that Robson is under the control of some force, possibly the seaweed. Jones actually agrees to listen, though she finds it preposterous.

 The control rig contacts them suddenly, and Baxter, the chief says they’re under attack, and they see seaweed and foam appearing, then the link goes dead.

 Jamie is searching for Victoria, but he cannot find her. Then, peering into the pipeline room, he sees her lying unconscious by the inspection platform. He finds a key and enters. She doesn’t respond at first and he’s afraid she’s dead and says, “If anything happened to you, I’d never forgive myself.” This shows us for the first time that he does feel strongly about her. She says the two engineers must have done something to her.

 Once more, she whines about getting into trouble. This time she continues, saying she’s tired of “one crisis on top of another”. He asks if she’s unhappy with traveling with The Doctor, but before they say any more, they hear the thumping once more. Jamie points at the observation deck in horror.

 The Doctor tells everyone they have to find the nerve center of the seaweed – it is a colony intellect and they have to destroy the nerve center to win. Jamie and Victoria arrive and summon him and the others to the observation platform, wherein they see seaweed amassing. The Doctor says it’s the advance guard, the first wave of the invasion, that the battle of the giants has begun… and the credits roll.

Episode 5:

 They keep trying to contact the rigs, but The Doctor says that the rigs have been taken over. He also warns them that destroying the rigs will only help spread the seaweed, the last thing they want to do. The Doctor speculates that the weed was first drawn up by the drill, and when the engineers went to clear it, they were taken over.

 The Doctor theorises that pure oxygen must be deadly to the seaweed and their slaves. Oak and Quill overhear this and head to the oxygen room, stopping to put on gas masks.

 Robson is located in his cabin; Jones insists on talking to him as they are old friends. Harris insists on accompanying her. Jones goes in first, alone and asks Robson to help her understand what is going on. She appeals to him to fight whatever it is that has happened to him. She pulls the authority bit, appealing to the man’s sense of duty, his pride, his reputation… but how successful is she?

 The Doctor is struggling for ideas how to defeat the seaweed. Everyone is looking to him and he fails to come with the answer, though he says something is in the back of his mind.

 Robson rises from his bed, seemingly hearing instructions, as he verbally responds, “yes… yes… yes…”. He slips out of his charmbers and attacks the guard posted outside his door.

 Harris receives a report that the oxygen supplies have been depleted. The Doctor warns everyone that someone in the staff have been compromised and Jamie sees Oak and Quill trying to slip away. Jamie runs after them and tackles Quill, though Oak gets away. Quill fights back and Victoria screams as Jamie punches Quill and the engineer goes down. Jamie is crowing about his punch, but The Doctor says he doesn’t think it was the punch – obviously, Victoria’s scream – it held up the mass in the Harris cabin earlier, too. Sonics are going to be the weapon I bet, and we’ve just introduced the sonic screwdriver, what what?

 The seaweed is trying to break out of the pipeline. The sheer panel in the observation deck bursts open and foam fills the room. An engineer is grabbed and pulled into the foam. As everyone tries to escape, the doors are closing and The Doctor wedges himself between the doors as Jamie looks for Victoria, but is not able to find her there and they slip through.

 Robson heads out the sea entrance from the facility, carrying an unconscious Victoria. He takes her to a vehicle and drives off.

 Klaxxons sound in the facility (will this have any effect on the seaweed or am I completely wrong in my guess?) Harris gives the order to find Robson.

 Robson drives dangerously down the road, reaching the airstrip, where a helicoper sits. He loads Victoria on the ‘copter and slips into the pilot’s seat to take off. Price sees the helicopter on the security monitors and tells Harris about Robson. The Doctor and Jamie arrive at the control room to find out that he has Victoria.

 The Doctor gets on the communicator to talk to Robson, but he tells him if he wants Victoria then he will have to “come over to us”. The Doctor and Jamie are taken in a helicopter to pursue, despite the fears of the staff. The Doctor hopes by following Robson, they’ll find the nerve center of the seaweed colony.

 Jamie and The Doctor are dropped off at the control rig, where Robson’s ‘copter has landed. They make their way into the rig, but it seems to be deserted. They hear Victoria calling out, but The Doctor cautions Jamie not to rush in, as it may be a trap.

 They hear the increasingly louder sound of the thumping. The last room in the corridor is filled with foam, a figure standing in the center, his body almost encased in weed, standing in the waist deep foam. Robson says, “Come in, Doctor, we’ve been waiting for you,”… and the credits roll.

Episode 6:

 Robson tells The Doctor that he is going to help them take over the world. Robson exhales toxic gas at The Doctor while Jamie frees Victoria and they slip out. Robson gives chase and Victoria screams, which forces him to stagger back. The Doctor tells Victoria to keep screaming and she does so, again and again, until Robson staggers back into the room.

 They make it to the surface of the rig, but the helicopter pilot either doesn’t see them or is afraid to land. They make for Robson’s ‘copter and The Doctor pilots it. The foam seems to try to hold on but they manage to lift off. The Doctor refers to Astrid, from THE ENEMY OF THE WORLD, saying he watched her fly one, so he thinks he can handle this one – however, he finds it much harder to handle than he expected.

 There’s lots of whoas and screams from Jamie and Victoria as The Doctor flies the helicopter. The other pilot comes on the radio and gives The Doctor some pointers.

 Jones and Harris argue over what to do, when The Doctor and his companions arrive back at the facility. The Doctor shares that they’ve discovered that sounds, especially Victoria’s screams, are the best weapon. The more noise they make, the better.

 After arguing with Harris, The Doctor finally gets him to agree to let them try. Victoria is asked to scream, but she finds it “silly”. Really? I want to throw her to the seaweed now. She finally screams for them and they record it – the plan is run it through amplifiers and blast it through the pipeline.

 They save the day and there’s rejoicing everywhere. Maggie and Robson are safe on the control rig. They say even Van Lutyens is okay. Victoria is upset, though, overwhelmed and wore out.

 Several hours later, The Doctor and his companions, Robson and the Harris(es) are having dinner together. They have some laughs and good food and company. Robson gets up and asks if he will see them tomorrow, but The Doctor says no. When Robson asks where they’re going, The Doctor says they haven’t decided, but Jamie chimes in that they wouldn’t get there anyways.

 Victoria is loathe to go; she doesn’t want to leave Jamie and The Doctor, but she doesn’t want to go, either. Jamie is upset, but The Doctor understands. She apologises, and Mrs. Harris offers to take her in. The Doctor says they’ll stay one more day to be sure that Victoria is absolutely sure.

 Robson checks in on Price, then the Chief Engineer. The Engineer says the impeller needs some repairs. Robson tells him to wait until the relief shift has arrived.

 Victoria is alone on the patio, deep in thought. Jamie comes out to find her. They talk about her staying; she explains that she couldn’t go back to Victorian times, she has no family there for her. She asks Jamie if he wouldn’t leave without saying goodbye first and he says of course he wouldn’t.

 The next morning, The Doctor and Jamie head out into the ocean to go back to the TARDIS while Victoria and the Harrises watch on. The Doctor and Jamie make it to the TARDIS and enter. Jamie watches on the monitor, sadly, worried. The Doctor asks Jamie where he would like to go and he replies, “I couldn’t care less.” The Doctor regards Jamie seriously, then says, “I was fond of her, too, you know, Jamie.”

 Victoria watches as the TARDIS dematerialises… and the final credits roll.

 Sadly, I’m not upset to see Victoria go. I wonder how she’ll adapt to the time period, but the way the writers handled her was not that enjoyable much of the time. Whine and cry and moan and bitch – like Polly when the writers decided she was a totally useless character, or Susan or Vicki for the majority of the time.
