Forensic psychologist and single mother Ann Bailey has joined forces with Montana Highway Patrol officer Bryce McCabe. An expert in untangling the motives of depraved minds, Ann is tasked to help solve the mystery of two murdered women doused with gasoline and set aflame. The deeper Ann and Bryce's investigation goes, the nearer they get to each other and to danger. After another murder hits close to home, Ann fears a clue is hidden in her own past. Only one thing terrifies her more than the reveal of a long-held secret. It's that the secret itself has put Ann into a killer's line of fire.
