After multiple women go missing, Agent Melina Shepard of the Tennessee Bureau of Investigation makes the impulsive decision to go undercover as a prostitute. While working the street, she narrowly avoids becoming a serial killer's latest victim; as much as it pains her to admit, she needs backup. Enter lone wolf FBI agent Jerrod Ramsey. Stonewalled by a lack of leads, he and Melina investigate a scene where a little girl has been found abandoned in a crashed vehicle. They open the trunk to reveal a horror show and quickly realize they're dealing with two serial killers with very different MOs. The whole situation brings back memories for Melina-why does this particular case feel so connected to her painful past? Before time runs out, Melina must catch not one but two serial killers, both ready to claim another victim-and both with their sights set on her.--
