Following on from the events on The Ark in Space, the Doctor, Sarah and Harry transmat down to Earth to find it not only habitable, but with people there. Not just people either, but someone that Sarah mistakes for someone she met before, and they’re conducting some nasty experiments.
Then, once they find their way back to Nerva Beacon, they find the Beacon being used for it’s intended purpose – but with all but 4 of the original crew wiped out by a mysterious plague of artificial origin… with the perpetrators behind that plague soon arriving to wage war on the traveling asteroid world of Voga.
The Fourth Doctor’s attempt to show Harry Sullivan the moon backfires thanks to the latter’s messing with the helmic regulator, bringing them and Sarah many thousands of years into the future to Nerva Beacon. Yet they are not the only ones to have found this orbiting ‘ark’ of humanity in cryogenic sleep. The spacefaring Wirrn have also found Nerva, and are looking to colonize.
Most of the time, the Doctor can never really know the outcome of his actions. But when he, Steven and Dodo run into an ark carrying the last of humanity to a new world, he finally gets to see the results first hand. After a simple cure for a plague and a 700 year jump forward he discovers that the unintended side effects and be quite severe.
The 10th Doctor and Martha drop by 1930’s New York City to find the city in the midst of the Great Depression and the Empire State building 6 months away from completion… only to find out that the Cult of Skaro have taken over the project.
Nothing is quite what it seems like when The Master is involved. Just because he’s in prison doesn’t mean he’s not up to his old tricks as Jo and the Third Doctor soon find out. Of course he’s not the only threat this time, but there’s also the arrival of a different breed of Silurians, the Sea Devils.
There’s the old well warn saying “I may not know art, but I know what I like”. Well it turns out that when it comes to the Mona Lisa, art doesn’t much like you either. Of course she’s not just a painting but some sort of alien creature trapped in the paint that has come to life and is looking for some family. Luckily Sarah Jane Smith and her crew are there to stop her… though Sarah might be a little hung up…
A warp ellipse draws the TARDIS onto what appears to be a stranded starliner. Nyssa and Tegan become separated from the Doctor; not in space, but 6 years into the past, while the Doctor has to deal with a curious schoolboy named Turlough, who has got himself mixed up with an old enemy. The Doctor’s old friend, the Brigadier, is enjoying life as a school teacher, but why doesn’t he remember the Doctor at all?
Things are getting a pit prickly as the Doctor and Romana II have an encounter with Meglos, a super intelligent cactus with aims for world domination. Of course he’s going to need to borrow a body, which he can also make look like the Doctor (while keeping the real thing tucked away in a time bubble). Not that a little Chronic Hysteresis Loop will stop the Doctor.
The old west beckons again, but this isn’t the wild west; just the town of Mercy. With 81 inhabitants, electronic lights, an alien doctor and a cyborg gunslinger lurking out in the desert. Naturally the Doctor is excited about the whole thing, though Amy and Rory less so. Of course the color of hats have nothing to do with anyone’s alignment… at least this time.
We return to the days of black and white as we join the Second Doctor, Jamie and Zoe find themselves right in the middle of it again as they stumbling upon the Gonds. A group of almost humans are the servers of the enigmatic Krotons. Of course now that they TARDIS has arrived they are going to finally put in an appearance.
