One Night in Miami...

In 1963, Cassius Clay nearly loses a boxing match to Henry Cooper at Wembley Stadium in London. At the Copacabana in New York City, soul singer Sam Cooke suffers through a performance in front of a cold, all-white audience. Returning home to Georgia, NFL player Jim Brown is received by family friend Mr. Carlton on a vast plantation. Carlton ladles praise on "the great Jim Brown," but when Brown offers to help Carlton move some furniture, Carlton uses a racial slur and informs Brown that he is not welcome inside the home due to Brown's blackness. Elsewhere, Malcolm X returns home and discusses his plans to leave the Nation of Islam with his wife, Betty.

On February 25, 1964, the men are all in Miami for Clay's title bout against Sonny Liston. Malcolm meets with Clay in a hotel room before the fight, and the two pray in a traditional Islamic fashion. That night, Brown is a ringside commentator and Cooke and Malcolm X are in the crowd as Clay upsets Liston, making him the world heavyweight champion.

Afterward, Malcolm invites the other three men to his motel room. Their hopes of a party are dashed when Malcolm makes it clear they are the only ones he invited. He wants to spend some time reflecting on their accomplishments, but tension between him and Cooke arises. Malcolm accuses Cooke of disloyalty to the black community by pandering to white audiences, and Cooke argues that his method produces greater economic empowerment for black artists. Clay informs the men of his plans to announce his conversion to the Nation of Islam, causing more tension. Brown discusses his plans to become a film actor, and wonders if it will go smoothly.

The conflict between Malcolm and Cooke escalates. Malcolm harshly ridicules the music Cooke has produced since finding success. Cooke insists his success and creative autonomy is itself an inspiration to the black community, and while he still cares about the black struggle in America, protest songs are not commercially viable. Malcolm confronts him with the success of Bob Dylan's "Blowin' in the Wind".

As they argue, it becomes clear that Malcolm's antagonism of Cooke is motivated, at least in part, by the activist's stress over his own life, especially his harassment by the FBI and fears about his schism with Elijah Muhammad. Malcolm is devastated to learn that Clay is having second thoughts about his conversion. He tells Clay that he is planning to form his own organization and asks him to join. Clay refuses, feeling betrayed by his mentor, and wondering if his conversion has been a ploy by Malcolm to attract attention to his new project. A knock at the door informs them that the press has gotten wind of the meeting. As Clay prepares to talk to the media, he asks Malcolm to come with him. When they leave, Cooke tells Brown that he has had similar thoughts about "Blowin' in the Wind" and has already written a song, but not yet performed it.

In the aftermath of the night, Clay officially changes his name to Muhammad Ali, while Malcolm's life is thrown into chaos as he suffers the consequences of his split with the Nation of Islam; his house is firebombed, but he completes his autobiography. Cooke debuts "A Change Is Gonna Come" on The Tonight Show. Brown leaves the NFL to pursue his movie career. The film ends with a title card with a quote from Malcolm on February 19, 1965, about the inevitability of martyrs for the cause, and that he was assassinated two days later on February 21.
