In a police station of East Los Angeles, California, Inspector Robbins is waiting for Detective Bradford at his office. Bradford soon arrives, dressed in a top hat and formal evening wear. He was called to work while on his way to the opera, and he protests the idea of working an unexpected assignment. But Robbins informs him that the case involves the "old house on Willows lake", which played a part in an earlier case investigated by Bradford. (This is a reference to the events of "Bride of the Monster"). The house was destroyed by lightning, but someone rebuilt it. A flashback scene establishes that the elderly Edwards couple had a terrifying encounter with the White Ghost by this house. Having heard the story, Bradford accepts the assignment to investigate the old house. Robbins assigns Kelton to escort the Detective, despite the protests of the man that ""Monsters! Space people! Mad doctors! They didn't teach me about such things in the police academy! And yet that's all I've been assigned to since I became on active duty"". The line is used to recall Kelton's experiences in "Bride of the Monster" and "Plan 9 from Outer Space", and to explicitly connect this film to its predecessors.
