Synopsis: Trying to get away from it all with a vacation to Benidom, the Doctor is plauged not by a case of "traveller's tummy", but by the TARDIS' faulty circuits. He lands instead on the world of Zom--and right in the middle of a rebellion. Zom is a world where emotions are seen by the ruling elite as abominations to be avoided. An active revolutionary group, the Zom Emotional People's Organization is out to change all that.
They believe that the ruling Brain Trust should be overthrown by a people whose emotions have been allowed to resurface. That won't be easy, though, since a rival rebel group, Big Hate, has invented a device that's getting out of hand. The Bloodbugs are cybernetic flesh-eaters, designed to attack only the government's "thought police". At first, the idea seems to work, but now the Bloodbugs are swarming towards the city. Since the Bloodbugs feast of the flesh of the emotionless, the city's innocent population is in equal danger to the "thought police". Can the Doctor find a way to help Z.E.P.O. achieve its aims, while controlling the huge problem unwittingly unleashed by Big Hate?
