Fred Mumford returns to Earth from the spirit world to open a business called 'Rentaghost' which offers ghosts, spirts and poltergeists on a daily or weekly rental basis and is having trouble paying the rent on his shop.
The shock of finding out his tenants are ghosts sends Mr. Meaker to the hospital with appendicitis. However, when the Rentaghost team visit him, they see an opportunity for a job - as hospital ward entertainers.
