When newly-arrived soul Cassie Parker refuses to believe she's no longer alive, Dead Detective Seamus is sent back to Life to learn what happened to her. He soon suspects it was murder, but why would someone kill the costume maker at a small Toronto theater? While Cassie struggles to accept being dead, Seamus tries to protect her less worldly sister Christy, who takes over Cassie's job as wardrobe mistress. Christy unknowingly wades deeper into danger, and Seamus senses an odd presence whenever her new boyfriend comes near. Along with murder and intended murder, Seamus has to solve a question he's never considered before: Can a guy be haunted when he's already dead?
