Heat

Jesse Warden is at the end of his rope. Imprisoned unjustly (or at least for the wrong crime), he spends half his time in solitary confinement and the other half fighting with convicts who want to kill him because he was once a cop. Then, at his lowest ebb, he is offered a way out. To earn his freedom, he must infiltrate a dangerous and reclusive religious cult in the mountains of the Idaho panhandle, a mission that turns out to be a great deal more perilous than his stay in prison.
