Fred Mumford returns to earth from the spirit world to open a business called 'Rentaghost' which offers ghosts and poltergeists on a dialy or weekly rental basis. He is sometimes helped, but more often hindered, by Davenport, a fussy Victorian ghost, and Claypole, a mischevious medieval poltergeist.

Fred Mumford and his fellow ghosts set out to exercise a ghost which has been terrorising London's Heathrow Airport.

Mumford and his colleagues decide to tell their landlord, Mr. Meaker, that they are really ghosts. The shock of this lands Mr. Meaker in the local hospital where the Rentaghost team offer to provide a conjuring act for the centenary celebrations. As ghosts they find it easy to vanish - but Mumford has some difficulty becoming visible again.
