A group of strippers accidentally kill a celebrity in a haunted graveyard and attempt to cover up their crime, but fear that their secret has gotten out when they are stalked by a mysterious psychopath on the one year anniversary of the terrifying ordeal. Real estate tycoon William O'Toole (Ryan O'Neal) owns a clandestine strip club that caters to an exclusive clientele. When Tom Kingsford (Tom Sizemore) hires the hottest girls in the Lingerie Lounge to be his personal companions for the evening, demented club regular Dave (Robert Carradine) follows the group as they drive off into the night, and take a shortcut through a cemetery with a dark reputation. Little does everyone realize that someone behind the scenes is pulling the strings, and when Tom is killed in a tragic accident, the girls quickly bury him and swear each other to silence. Exactly one year later, a gruesome discovery prompts the surviving strippers to seek safety in numbers by throwing a slumber party. But later, when the corpses start piling up, they realize that the party has been crashed by a psycho killer who seeks to ensure that they pay for their sins.
