A quick glimpse at the cast for this film would make any horror fan giddy with glee. The actual movie doesn't live up to those high expectations, but it's far from being all bad. Desi Arnaz Jr. (!) plays an author who makes a crazy $20,000 bet with his publisher that he could write a great novel in only 24 hours. To do so, the publisher gives him the keys to an old abandoned house where he won't be disturbed. Not true. Once he gets there he is interrupted by a multitude of guests including a family which consists of John Carradine, Sheila Keith, Peter Cushing and Vincent Price. They are gathered there in a twisted family reunion to release their brother from the room he's been imprisoned in for forty years. Even Christopher Lee drops by as Corrigan, the man who has just purchased the house. Soon, they realize that the caged brother is loose and out for revenge.
