New Series Episode 138:


The Doctor takes Bill to a human colony in the far future. There they discover an empty city, where every need is satisfied by a nanobot swarm called the Vardies. Exploring further, the time travellers discover the remains of the advance team despatched to prepare the city for colonisation -- all murdered by the Vardies, who have spontaneously begun to target anybody who expresses a negative emotion. The Doctor realises that the city is a giant deathtrap which must be destroyed, but it falls to Bill to discover the real reason for the Vardy mutiny.
