In the winter of 1968, the prairie city of Saskatoon is ravaged by a string of savage rapes. A few months later, fears are bolstered when a young nurse is found raped and murdered in an alley near her home. Police attention is brought to a young man named David Milgaard - the evidence on him is thin, but the court finds him guilty. After spending nearly 20 years in prison, David continues to plead his innocence. Through the undying faith of his mother, the real killer is slowly discovered to be a man named Larry Fisher. Approaching the turn of the century new DNA technologies finally exonerate David and plant the real killer, Larry Fisher, behind bars for life.
