We investigate the story of David and Catherine Birnie, Australia's most sadistic husband and wife killing team who tortured, raped and murdered four women in 1986. We also look into the murder of Call Girl Roslyn Watson which had remained unsolved for more than 15 years and would have stayed that way if it wasn't for the tenacious efforts of a bright young Western Australian Police Detective.
