Detectives John Cardinal and Lise Delorme have grown closer as friends and partners. There’s a strong bond between them that transcends the job, a bond that deepens all the time and yet remains largely unspoken. But when a seemingly mundane missing persons case turns into a spree of nightmarish murders, the ensuing investigation pushes them to their limits as detectives and partners, forcing them each to face what their future holds.
