However, when he discovers this he decides to take action and promotes Jimmy, his Head of the Complaints Department, to Programme Director. Jimmy decides that a series of variety spectaculars are what the public want and sets about hiring the acts. But obstacles are put in his way and he discovers that the NBG has its own cluster of wannabe variety stars.

Capt Viking and his incompetent fire crew accidentally foil a plot to steal the crown jewels.
