Bigger "Big" Thomas, a young African American man, lives with his mother and siblings in Chicago. Half-heartedly involved with a girlfriend, he sports green hair and a punk jacket, smokes weed, and carries a pistol but rebuffs his buddy's easy-money scheme to knock off a corner store. Full of self-determination, Big accepts a job as the chauffeur for wealthy businessman Will Dalton's family. Moving into their mansion, he begins driving Dalton's vehemently progressive daughter, Mary. But his involvement in an accidental death places Big on a collision course with the powerful social forces pitted against him.
