Farris Jorn has Post-Traumatic Stress Disorder. Or at least, that's what his therapist, Dr. Ligenfelter, tells him. In order to treat his disorder, Farris undergoes a hypnosis session that will allow him to recall the incident in his past, which has led to his PTSD, an incident that his mind has shut out from his conscious memory.
In a vivid flood of images and fragmented memories, Farris recalls his time in Afghanistan as a solider for the United States military. On a mission to capture a high ranking enemy combatant, Farris and his fellow soldier and friend, Clint Trucks, are ambushed and taken prisoner. For hours the two soldiers endure crippling torture sessions that push them to the very brink of death. Farris feels an uncontrollable rage well up inside of him. His pulse pounds a fevered beat against the walls of his veins. His muscles tighten. And then, nothing. Farris blacks out.
When he awakens dead bodies surround him. Of course, the bodies weren't just dead, they were eviscerated, literally ripped limb from limb.
