Three desperate souls must fight their way out of a dead-end world in this bracing, gut-punching glimpse into America's dark underbelly. Earl (Jamie Bell: Billy Elliot, Fantastic Four) is a struggling ex-marine and father determined to make a better life for his family--no matter what it takes. Angus (Frank Grillo: Captain America: Civil War), is a violent, unhinged drug dealer, who leaves a trail of death and destruction in his wake. And Delia (Margaret Qualley: The Nice Guys), 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. Blending an unflinching and brutal vision of life on the extreme margins.
