Plot summary

In 1964, Dr. Martin Luther King Jr. of the Southern Christian Leadership Conference (SCLC) accepts his Nobel Peace Prize. Four black girls walking down stairs in the Birmingham, Alabama 16th Street Baptist Church are killed by a bomb set by the Ku Klux Klan. Annie Lee Cooper attempts to register to vote in Selma, Alabama but is prevented by the white registrar. King meets with Lyndon B. Johnson and asks for federal legislation to allow black citizens to register to vote unencumbered, but the president responds that, although he understands Dr. King's concerns, he has more important projects. King travels to Selma with Ralph Abernathy, Andrew Young, James Orange, and Diane Nash. James Bevel greets them, and other SCLC activists appear. FBI director J. Edgar Hoover tells Johnson that King is a problem, and suggests they disrupt his marriage. Coretta Scott King has concerns about her husband's upcoming work in Selma. King calls singer Mahalia Jackson to inspire him with a song. King, other SCLC leaders, and black Selma residents march to the registration office to register. After a confrontation in front of the courthouse, a shoving match occurs as the police go into the crowd. Cooper fights back, knocking Sheriff Jim Clark to the ground, leading to the arrest of Cooper, King, and others..
