It seems like only the aftermath of a wild night when Freddy Johnson wakes up one morning and can't remember a thing that happened to him the previous day. But it quickly turns out to be much more when Freddy finds an angry voice mail from his girlfriend, Lauren, and has a complete stranger show up at his house only to lead him to Lauren's corpse stuffed in the trunk of his car. With the police on his tail, Freddy has to struggle to regain his memories. Did he really kill Lauren, and why? What happened the night before? And who is this mysterious, eerily calm stranger - moreover, is he really there, or is he but a figment of Freddy's unraveling mind?
