Fighting for Immortality uncovers the action and back-stories of four huge boxing matches spanning the first two decades of the millennium. Four British boxers cross 'the pond' to fight four top Americans in their own backyard. The outcome was even. Two British victories, two American victories, including one amazing upset. One boxer cements his all-time great legacy while taking on an opponent burdened with his own country's weight of expectation. The best boxer of his generation proving once again that he was on another level. Meanwhile, Las Vegas had never seen a fight-week like it, as fans of the British fighter took the city by storm. Two older, indefatigable fighters, both determined to prove who was the best on the planet in a bout that began with a potentially racially charged gibe. Finally, in one of the biggest shocks the sport of boxing has produced, the victor forever staked his place in boxing history.
