Ali gets assigned to work the cold case of Jessica Tyson. Gerald Lee had confessed to the murder, but because his confession was a direct result of a cop threatening his life, the case was thrown out of court, and Gerald Lee protected under the double jeopardy law. It isn't long before Ali becomes convinced that the evidence against Lee isn't quite as good as they thought it was. Nicco, Len and Mickey continue to investigate the Ambleton case and Drainie's connection to Desmond Cage, and soon learn that Drainie had been buying computers and computer parts on a regular basis. While trying to further the investigation, they learn the mounties are also investigating Drainie, and have taken the squad's best evidence with them.
