Three desperate souls must fight their way out of a dead-end world in this bracing, gut-wrenching glimpse into America's dark underbelly. Earl is a struggling father and ex-Marine determined to make a better life for his family — no matter what it takes. Angus is a violent, unhinged drug dealer who leaves a trail of death and destruction in his wake. And Delia is a haunted woman who will do anything to escape a life of crime she can no longer bear. In their kill-or-be-killed world, all roads lead to the Donnybrook: an illicit backwoods cage match where bare-knuckled fighters brawl for a shot at a $100,000 prize. It's either a last-ditch chance at redemption — or a death sentence.
