 FBI agent Jake Malloy just can t nail a serial killer who s been targeting cops. The killer has already killed nine cops. Not only does the killer despise policemen, but he also has a grudge against Malloy for pursuing him during a string of prostitute murders four years ago. The killer finally decides to hit Malloy where it hurts, killing one of Malloy s friends on the force, and brutally killing Malloy s fiancé Mary. The grief sends Malloy off the deep end and causes him to become alcoholic, forcing Malloy s colleague, Detective Hendricks, to sign Malloy up at a remote detox clinic in a snow-covered part of Wyoming. The clinic specializes in rehabilitating alcoholic cops. But the killer murders another patient and assumes the patient s identity at the clinic. While Malloy participates in group therapy sessions, the killer starts killing the patients. Among the endangered patients are Jaworski, Slater, Noah, Conner, and a dozen others, one of whom must be the killer. One by one, the patients start falling prey to the killer and, starting with the facility s director, Doc, the killer starts targeting the staff as well.
