In 1940, Thurgood Marshall is a young lawyer for the NAACP who criss-crosses the country defending innocent African-Americans from unjust indictments in court. His latest case is in Bridgeport, Connecticut where an African-American chauffeur is accused of rape of a wealthy white society woman. To admit Marshall into the local Bar, insurance lawyer Sam Friedman is picked over his objections to do introductions in court. However, Friedman's commitment changes drastically when the racist judge forbids Marshall to speak in court, forcing Friedman to act as lead counsel. Now in an intolerable situation for the pair, Marshall must guide his new compatriot through this criminal trial even as Friedman endures not only this unfamiliar area of law, but also the bigoted pressure he now must share. However, the case proves more complex than either anticipates with unexpected twists and turns even as it becomes a vital one that would define two careers as well as the fight for justice in America.
