Avid hunter Tom Newcliffe (Lockhart) invites seven guests to his high-tech estate in the hopes of revealing one of them as a lycanthrope. Functions as both a straightforward horror piece as well as a detective story, with a 30 second "werewolf break" (a la William Castle) just before the climax, allowing each viewer to decide for himself who the werewolf is.

Great setting and game performances from all involved help make this an enjoyable late night escape. Cushing, Gray always a pleasure to watch.

Also known as Black Werewolf.
