This is a documentary film that covers the lives, careers and contrasting personalities of British heavyweight boxer Frank Bruno and the American Mike Tyson. From their difficult starts in life, that led them both to boxing as a path to avoid a life of crime, their boxing careers would be closely linked from the early days where they sparred together and culminating in two World Heavyweight Championship fights that defined their boxing legacies. Tyson was an fast vicious animal in the ring whilst Bruno lacked the speed but was a destroyer who could finish a fight with a single punch - their personalities outside the ring were just as contrasting as their boxing styles. This documentary plots the rise and fall of both fighters in both their boxing and personal lives and culminates with the two meeting up for the first time in decades to reflect on their entwined boxing journeys and reflect on their lives and careers.
