After twenty seven years in the British army, Alfie returns home with his family planning on sittiing back, relaxing and enjoying civilian life. But after a close family member is attacked, along with a string of other events, Alfie realises that life is not as rosy as he expected, and begins to struggle with every day life. Desperate to get his life back on track, Alfie refers himself to a group therapy where he meets more military veterans who are in similar circumstances to his. But everything is not what it initially seems, and Alfie finds himself being dragged into a life of violence, revenge and vigilantism. Will the law catch up with the brotherhood? Or will Alfie become a victim of his own rage?
