An English family of six takes in a pregnant woman who disappears shortly after giving birth. They raise the baby girl as their own, but over the years the strange deaths of their children make them consider whether the little girl is more than she appears.

A married couple, lost in the woods, stumbles across a creepy mansion and its inhabitants - an overly-kind old woman and deadly wolf children that scour the country-side looking for victims. Originally an episode of British horror anthology TV series, Hammer House of Horror, that later received a feature release in the United States.
