The Rats Are Coming! The Werewolves Are Here!
The daughter in a family of werewolves decides to put an end to the family curse. Man-eating rodents are only playthings for a 19th-century family who have a unique problem with the full moon.
The film centers on the eccentric Mooney family who live in a large house in rural England in the year 1899. The invalid patriarch 'Pa' Mooney (Douglas Phair) is a retired medical doctor who claims to be 180 years old. His eldest daughter, Phoebe (Joan Ogden), more or less cares for him and is head of the household. His eldest son, Mortimer (Noel Collins), is a businessman who conducts the finances of the family and contributes to the family income. Younger daughter Monica (Hope Stansbury) is a sadist who keeps live rats as pets and frequently mutilates them and other small animals. Youngest son Malcolm (Berwick Kaler) is a halfwit with animalistic tendencies; the family keeps him locked in a room with live chickens. The family has a secret: they are all werewolves-natural born werewolves who transform once a month on the night of the full moon. Pa Mooney has been researching for years to find a way to break the family curse.
Youngest daughter Diana (Jackie Skarvellis) returns home from medical school in Scotland with a new husband, a former classmate named Gerald (Ian Innes), of whom Pa Mooney heartily disapproves. Pa tells Diana that she is the last hope the family has to overcome the ancient curse, since she is the only member of the family who does not turn into a werewolf on the night of the full moon. Will Diana succeed? Diana is eventually revealed to have other plans, and on top of that, she has her own secret as to why she is "different" from the other werewolves of the Mooney family.
