After receiving a frantic call from Sam (Jared Padalecki), who has been missing for over a week, Dean (Jensen Ackles) races to his brother's side. He finds Sam covered in blood, but unable to remember anything that happened.
Upon investigation, the brothers are horrified to discover a tape that shows Sam killing another hunter in cold blood, causing Sam to believe his evil side is finally taking over.
