Paradise Towers
Paradise Towers is the second serial of the 24th season in the British science fiction television series Doctor Who, which was first broadcast in four weekly parts from 5 October to 26 October 1987.
Plot
The Doctor and Mel Bush, looking for a swimming pool, land in Paradise Towers, a luxurious 22nd century high rise apartment building now fallen into disrepair and chaos. The building is divided between roaming gangs of young girls called Kangs, grouped in colour theme, and the Doctor and Mel encounter the Red Kangs. They have just discovered the death of the last Yellow Kang and are plotting how to attack the Blue Kangs. Elsewhere in the Towers, one of the Caretakers - who act as 'Judge Dredd' style policemen – is hunted down and killed by a robotic cleaner, which appeals to the sadistic Chief Caretaker when he overhears the death.
The Chief sends a squad of Caretakers to arrest the Red Kangs and in the ensuing confusion the Doctor is split from Mel and captured by the Caretakers. Mel meanwhile heads off to one of the still occupied apartments in which two elderly ladies ('rezzies') live. Tilda and Tabby explain that all the able bodied men left the Towers to fight a war, leaving behind only the children and the elderly. The only other man still loose in the Towers is Pex, a would-be hero, who appoints himself Mel's guardian.
