Smokey Dalton and Jimmy, the young boy he protects, have settled into a new life on Chicago's South Side. But when Smokey gets hired to investigate the death of a black man in a local park, he realizes that the murder might not be an isolated case. The Chicago Police Department doesn't really investigate black deaths, particularly near the South Side. Smokey thinks the case easy, until he digs deeper into the history of the area, a history that includes gangs, racism, and secrets so dark they threaten his very existence.
