"A Soldier's Story" is set in WWII, and it's about the murder of a black Army sergeant. It's a whodunit that explores the racism and segregation that existed in the Army, while a black Army lawyer tries to track down the killer. It's an insightful, probing look into racism between whites and blacks as well as among blacks themselves.
