After his death, Fred Mumford wants a second chance at achieving the success that eluded him in life. Coming back to Earth as a spirit, he recruits a Victorian gent and a medieval jester to set up 'Rentaghost', a supernatural service for wanted hauntings.
Harold is away but has forgotten to light the central heating boiler, leaving Ethel cold in the house; Mr Claypole tries to help bring a pantomime dragon to life and also hires Susie Starlight as the Perkins' cleaner.
Whatisname Smith returns, looking to redeem himself by taking on a position of authority. However, when he's put in charge of Rentaghost, the power goes to his head and he becomes a tyrant.
Villainous McSprite McDonald McDougle, who knew McWitch in life, attempts to join the team, but when they reject him, he vows revenge.
With the Meakers' car stuck in the Perkins' kitchen, it's up to Mr Claypole to distract the neighbours by posing as a sanitary inspector while the rest of the ghosts remove the car.
The ghosts try to come up with new money-making inventions, but McWitch's hair-grow potion and Mr Claypole's 'self-propelled bed' don't quite work.
