Based on true events, the movie follows Alaskan trooper Jack Holcombe who needs to find evidence against Robert Hansen, a serial killer who abducts young girls, then tortures and sexually assaults them before he kills them. To do this, he asks Cyndy Paulsen, one of Hansen’s victims that managed to survive his torture, to help him, but he finds out that she’s a junkie and has trust issues that need to be resolved first.
