The film opens with a man who decides to visit a house that has reputation of being haunted. He's frighten away & later learns of the manor's history.
It seems many years ago two men fought over money & the ownership of the house. One thing leads to another and one of them is murdered by way a heart attack. The ghost of the dead man comes back to haunt his murderer.
While this genre has been done before, I still recommend this film for its atmosphere & haunting music score. Its the kind of film you can watch with the lights off, still be entertained & not have nightmares about it. This is one of actor Laurence Harvey's earlier works & he shines in this film although some may think his acting is over-the-top. It works here because his character is slowly being driven insane.
When searching for this film, try rental stores that specialize in non-mainstream films. I found this gem by accident in a rental store that actually has a section for British films.
