Wouldn’t you like to know what a poltergeist is?

The engagement of Archie, a young doctor, to night club artiste Frieda sets off a sequence of eerie and seemingly unexplainable events, all starting with a strange, cruel warning on the telephone.

As the supernatural mysteries continue, a shocking murder takes place – and that can’t be explained by a ghost.

Dr Basil Willing steps in to help the four people involved in these hauntings answer the question: Could I have committed a murder without knowing it?
