On one incredible night in 1964, four icons of sports, music, and activism gathered to celebrate one of the biggest upsets in boxing history. When underdog Cassius Clay, soon to be called Muhammad Ali, (Eli Goree), defeats heavy weight champion Sonny Liston at the Miami Convention Hall, Clay memorialized the event with three of his friends: Malcolm X (Kingsley Ben-Adir), Sam Cooke (Leslie Odom Jr.) and Jim Brown (Aldis Hodge).
