The Doctor takes the TARDIS into the future where many great scientific leaps are taking place. But every new advance has its risks - and some of these risks are deadlier than others.

The Doctor and Sarah land on the space-station Daedalus on the day it makes history. The first journey through hyperspace has just been completed. But it hasn't gone as smoothly as posterity suggests.
Something terrible is happening - and the clock is ticking down.

Producer David Richardson said: "The Doctor and Sarah Jane head out among the stars... and they're indomitable! After the cosily Earth-bound Ministry of Death, the travellers visit other worlds and other times in Lethal Progress, which, as the title might suggest, finds that scientific advancement doesn’t always benefit the human race."
Writer John Dorney explained his episode: "I came into this story wanting to write something with a bit of horror but in a science fiction way. I was looking at different fictions for inspiration, like The Great God Pan and Event Horizon. Then I began to think about doing the whole thing as one long continuous scene; we've had a few 'single take' films like that in recent years, and I was curious to see what that would bring to a Doctor Who story."
