1970s British horror starring Calvin Lockhart and Peter Cushing. A variety of guests assemble at the lodge of wealthy big game hunter Tom Newcliffe (Lockhart), each of them in some way possessing a past involvement with cannibalism or murder. Newcliffe informs them that he is aware of their dark secrets and reveals his purpose in inviting them all together: one of his guests is a werewolf and he wishes to hunt him down.
