A meandering tale of an heiress who begins to believe that she is a werewolf prone to escaping from her plush London home at night and savagely killing people. It could just be an early example of a serial killer because we see scant evidence of a she-wolf; indeed there are no special effects employed at all in this very low budget horror film. Sara Haden has something of the "Danvers" about her as the aunt and Dennis Hoey once again does the business as the police inspector. It's worth watching, but all rather silly.
