Dr. Paul Kersey is a surgeon who only sees the aftermath of Chicago violence when it is rushed into his ER - until his wife and college-age daughter are viciously attacked in their suburban home. Hungry for revenge, Paul takes matters into his own hands, hunting down his family's assailants to deliver justice. As the anonymous slayings of criminals grabs the media's attention, the city wonders if this deadly vigilante is a guardian angel or a grim reaper. Paul Kersey becomes a divided person: A man who saves lives, and a man who takes them; a husband and father trying to take care of his family, and a shadowy figure fighting crime; a surgeon extracting bullets from suspects' bodies, and a vigilante called "The Grim Reaper" who detectives are quickly closing in on.
