Three months after the assassination of John F. Kennedy, two prizefighters named Charles “Sonny” Liston and Cassius Marcellus Clay Jr. stepped into a boxing ring in Miami to dispute the heavyweight championship of the world. Liston was a mob fighter with a criminal past, and rumors were spreading that Clay was not just a noisy, bright-eyed boy blessed with more than his share of the craziness of youth, but a believer in a shadowy cult: the Nation of Islam. Neither could be a hero in the eyes of the media.Against this backdrop of political instability, of a country at war with itself, in a time when ordinary African-American people were maimed and killed for the smallest acts of defiance, Liston and Clay sought out their own individual destinies.
