Plot
Most of the known residents of L.A. are anonymously invited to a dinner party in their honor at a mysterious cliffside mansion. Upon their arrival, their host is revealed to be Swiper, who states he has become a pacifist thanks to his new girlfriend, Selena, and wishes to repent for all his wrongdoings. Early into the night, as Swiper and Selena go to the kitchen, Wallace's new and embarrassing overweight girlfriend, Stephanie, is mysteriously shot and killed when she sits in Swpier's seat, leading the guests to believe that James intends to murder them all. They try to leave, but lightning from a thunderstorm strikes a tree, causing it to break the bridge while the causeway is flooded. After discovering that Stephanie's body has disappeared and returning amidst accusations, Swiper pleads ignorance before he too is murdered in front of the guests by an unseen killer with a knife during a power outage, causing Selena to faint. Trapped on the remote estate with no way of contacting anyone due to the storm and being out of cell phone range, the guests realize that the killer is among them.
