One Night in Miami theorizes what happened when four famous men got together in a small hotel room after the world heavyweight boxing championship. Instead of partying like crazy, they got into serious discussions about racism in America. One of the men, Cassius Clay, planned to upend expectations by announcing a change of faith and name. Under leadership and guidance by another guy in the room — Malcolm X — Clay aimed towards a different role as Muhammad Ali, the newly crowned heavyweight champion of the world. Malcolm hoped the two other men in the room — football player Jim Brown and singer Sam Cooke — would join the movement and use their influence to forcefully demand racial parity.
