David Haye. Unified world cruiserweight champion at twenty-eight, heavyweight champion at twenty-nine - on course to join the pantheon of boxing greats before injury and defeat in the ring seemed to put an end to his career. 4 years later, he's in the fight of his life as he undergoes radical, experimental surgery and trains harder than ever for one last comeback, one last chance to become a legend. With 2,000 hours of unprecedented, intimate access filming over 9 years, this is an extraordinarily personal portrait of a man struggling with anxiety, depression and self-belief and what it takes to achieve his dreams, what it takes to become a champion.—Dael Poulter
