Detective Jerry Commanda finds a confused, red-haired woman alone at a roadside bar with a bullet in her head. Red has no memory of who she is, how she got there, or who shot her. Even after the bullet is removed, she can’t remember anything. Commanda turns the case over to Detectives John Cardinal and Lise Delorme, who must protect Red while trying to uncover her identity and shooter.

Detectives John Cardinal and Lise Delorme identify the latest body as a local gun thief, their only suspect. Tracking the victim’s final days leads them to the local Northern Raiders biker gang, so they enlist the help of an expert, Staff Sergeant Alan Clegg from the Ontario Police Department (OPD).

Detective Cardinal and Delorme retrieve security footage of Red that helps identify her as Terri Tait, a student from Vancouver, BC.

Having tracked down Terri, Cardinal gains her trust. Terri’s recovered memories give the team new information to work with and they make progress tracking Terri’s shooter.

John and Lisa connect evidence from a new crime to a ritualistic murder and Terri's memories help make a connection to a possible suspect.

John and Lisa race to find Ray before he kills Terri and her brother. A betrayal threatens Cardinal and Delorme's case and their lives.
