Joe Carman is a 39-year-old mixed martial arts fighter. He also works in the boiler room of a ferry, and has four daughters, an angry ex-wife, and alcoholic father. To top it all off, his current wife has no idea he has started fighting again. Although this sounds like a complex narrative drama, it is actually a documentary. Filmed over the course of three years, a story unfolds of a man desperate to continue fighting for something he himself cannot even quite explain, despite growing post-concussion syndromes and the very real risk of tearing his family apart. How far will Joe go to prove something to himself?
