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.
