On the bank of a river lies the naked body of a murdered girl. At the nearby high school, one of the students boasts to Matt (Reeves) and his friends that he killed her. Drunk and stoned, the doubting teens venture to the river only to discover that he is in fact telling the truth. They decide to form a wall of secrecy, but Matt is uncomfortable about their silence and has to decide between exposing the criminal and keeping quiet for the rest of his life.
