This documentary examines the life of the charismatic Muhammad Ali and attempts to explain how he overcame many obstacles to become a great American hero. Black-and-white footage along with color takes viewers through the extraordinary life of a young and brash fighter by the name of Cassius Clay. He is shown as time goes by changing his name, refusing to fight in Vietnam, garnering an awesome boxing record of 56 wins and five losses, having his heavyweight championship title stripped from him, and publicly fighting Parkinson's disease. Plenty of Ali's memorable rhyming and outrageous quotes are included.
