An explosive documentary which examines the increasingly taut relationship between the American police and its citizens, this film is told through the story of William 'Dub' Lawrence, a former sheriff who established and trained his rural state’s first SWAT team only to see that same unit kill his son-in-law in a controversial standoff 30 years later. Driven by an obsessed sense of mission, Dub uses his own investigative skills to uncover the truth in this and other recent officer-involved shootings and SWAT team raids, while tackling larger questions about the changing face of police violence across America.
