Los Angeles, 1963: African American Korean War veteran Harry Ingram earns a living as a news photographer and occasional process server: chasing police radio calls and dodging baseball bats. When Ingram hears a call over the police scanner to the scene of a deadly automobile accident, he recognises the vehicle described as belonging to his good friend and old army buddy, the white jazz trumpeter Ben Kinslow, with whom he'd only just reconnected. The LAPD declares the car crash an accident, but when Ingram develops his photos there are signs of foul play. Ingram feels compelled to play detective, even if it means putting his own life on the line.
