The Doctor, Romana and K-9 visit Brighton out of season. Whilst the Doctor seems content to sit on a deck chair on the beach, Romana wants something more. She asks K-9 for a list of recreational facilities in the galaxy, and they settle upon the Leisure Hive on Argolis.
The surface of Argolis is a radioactive wasteland after a twenty minute war with the Foamasi. The Argolins themselves have been left sterile. The pride of the Hive is the new Tachyon Recreation Generator. Recently the Hive has been loss making, and an Earth agent has been trying to get Mena to sell to the Foamasi.
Pangol objects to the sale. Mena herself believes that she will be rejuvenated by Earth scientist Hardin. Hardin is a fraud, and the Doctor and Romana are arrested on suspicion of killing him.
While experimenting with the TRG the Doctor ages considerably. Pangol reveals himself to have been created by the machine. He plans to create an army of duplicates of himself to attack the Foamasi. Foamasi invaders reveal themselves to be government agents and unmask Fomasi saboteurs.
Instead of the army Pangol planned the TRG turns Mena and Pangol into younger versions of themselves.
