Otis has everything he needs for the prom: the corsage, the convertible, the cool baby-blue tux (not to mention the fully equipped torture chamber in his basement). He even has the girl - a pretty blonde he's named Kim - who is dying to be his date. Literally. Sometimes pizza guy and full-time psycho, Otis thinks he's a wicked dude…until he meets the Lawsons, his latest victim's happy suburban family. The Lawsons aren't happy anymore…and they have a truckload of power tools.
