Girly (Vanessa Howard), a fetching but evil-minded schoolgirl, shares a dark hobby with her oddball household: she lures unsuspecting men to their mansion on the outskirts of London, then engages them in "games" that inevitably end in their deaths. The horrific family project runs smoothly until Girly brings home a new friend (Michael Bryant) who's operating under his own set of rules. Soon, he turns the entire household upside-down.
