'The Leisure Hive' (4 Parts) Story Code '5N' by David Fisher

Following an unsuccessful holiday in Brighton, the Doctor and Romana decide to visit the Leisure Hive, a galactic entertainment centre on the planet Argolis. The planet surface is an uninhabitable wasteland, following a twenty-minute nuclear war between the Argolins and their enemies, the Foamasi; as a result of the radiation, the Argolins are a sterile, dying race. After mysterious accidents occur with the Hive's main attraction, the Tachyon Recreation Generator, Mena, the Argolin leader, is put under pressure by her Earth agent, Brock, to sell the Hive to the Foamasi - an offer that is opposed vehemently by her son Pangol. Mena believes that she can be rejuvenated through the Tachyon experiments conducted by Hardin, an Earth scientist, but the Doctor and Romana arrive during one of the experiments, and realise that it has been faked. Hardin's assistant discovers that some Foamasi have broken into the Hive, but when he is found strangled with the Doctor's scarf, the two Time Lords are arrested under suspicion of the murder. The Doctor and Romana are allowed to work under arrest with Hardin, but when the experiment goes wrong, the Doctor is aged considerably. As Mena starts to die, Pangol, now revealed to be a creation of the Tachyon Generator, takes over the Hive and attempts to use the generator to duplicate himself into an army that will fight the Foamasi. But the Doctor has hidden in the machine beforehand - he is rejuvenated and an army of Doctors is created instead. The Foamasi invaders reveal themselves to be government agents, and unmask Brock and his assistant, Klout, who are in fact renegade members of a Foamasi group known as the West Lodge, who are attempting to secure the Hive for their own ends. After the army of Doctors disappears, the Time Lord uses the Randomiser from the TARDIS to reconfigure the Generator, restoring Mena's youth and causing Pangol to become a baby.
