Ted is a man trying to deal with his werewolf curse while living with his sister, her son, and the family dog. He soon begins to get out of control, becoming a potential threat to his family. Thor, the family dog, takes matters into his own paws and battles the werewolf.
This film presents the idea that dogs can sense the werewolf curse even when said werewolf is in human form; a convention first introduced in The Wolf Man. It also shows a werewolf being killed by conventional violent means, in this case getting mauled by a dog.
