The TARDIS lands on a spaceship ten million years forward in time, heading for the planet Refusis with some of the last members of the human race (as well as other animals from Earth). First a virus from the distant past threatens humanity, and then as the TARDIS moves forward in time humanity is now under siege by their own alien servants, the Monoids. Can the Doctor, Dodo, and Steven save humanity?
This is Dodo's first full story, having only one scene at the end of "The Massacre of St. Bartholomew's Eve." She makes an excellent debut by infecting the last dregs of humanity with her cold, thus almost being responsible for the genocide of homo sapiens. What a way to make a splash! If nothing else, it's something to talk about at parties. ("So what have you done lately?" "Oh, wiped out the human race.")
It's been ages since I've seen this story, and most stations that still show Doctor Who don't air the Hartnell episodes. It's due for a video release in England soon, though, and in the meanwhile you can also read the novelization. Make sure you don't miss the scene where the Doctor ejaculates (p. 17) and then, even better, Dodo (p. 76). What this says about our adorable Ms. Chaplet, I'm not sure.
Dodo reveals that she actually paid attention in school, able to identify various animals and plants at just a glance. She also shows her kleptomaniac tendencies, swiping clothes out of the TARDIS wardrobe room without bothering to ask. Dodo also starts assigning names to anyone and anything she finds—the Ark, the members of the Refusian race, and so forth. Perhaps it's like a cat marking its territory?
At any rate, for Dodo fans this is a must-see episode. In the words of Dodo herself, "Fab!"
Dodo Chaplet, Art Critic: "Doctor, look at these fab pictures!"
Dodo prepares to doom humanity: "I'm not snivelling. It's me nose running again."
Dodo fesses up to the truth: "It's not me nose that's running any more. I'm crying this time."
Dodo's shout of joy: "That's gear!"
Dodo tries to wipe out humanity with her germs. Gooooo Dodo!
Think, Dodo, think! You can do it!
And here we have a nice constipated look.
I think Dodo's found herself a new friend...
