 Rural Mississippi in the 1940s: Lucas Beauchamp, a local black man with a reputation of not kowtowing to whites, is found standing over the body of a dead white man, holding a pistol that has recently been fired. Quickly arrested for murder and jailed, Beauchamp insists he s innocent and asks the town s most prominent lawyer, Gavin Stevens, to defend him, but Stevens refuses. When a local boy whom Beauchamp has helped in the past and who believes him to be innocent hears talk of a mob taking Beauchamp out of jail and lynching him, he pleads with Stevens to defend Beauchamp at trial and prove his innocence.
