Martin Luther King, Jr. and the Southern Christian Leadership Conference (SCLC) come north to help Chicago's civil rights leaders in their nonviolent struggle against segregated housing. Their efforts pit them against Chicago's powerful mayor, Richard Daley. When a series of marches through all-white neighborhoods draws violence, King and Daley negotiate with mixed results. In Detroit, a police raid in a black neighborhood sparks an urban uprising that lasts five days, leaving 43 people dead. The Kerner Commission finds that America is becoming "two societies, one black, one white, separate and unequal." President Lyndon Johnson, who appointed the commission, ignores the report.

A call to pride and a renewed push for unity galvanize black America. World heavyweight champion Cassius Clay challenges America to accept him as Muhammad Ali, a minister of Islam who refuses to fight in Vietnam. Students at Howard University in Washington, D.C., fight to bring the growing black consciousness movement and their African heritage inside the walls of this prominent black institution. Black elected officials and community activists organize the National Black Political Convention in Gary, Indiana, in an attempt to create a unified black response to growing repression against the movement.
