Boston in the early 1990s was the armored car robbery capital of America, and at the center of the chaos was a square-mile neighborhood known as Charlestown. This documentary follows the elite FBI task force assigned to take down Anthony Shea and his “Minuteman” crew, a group of professional thieves who operated with military precision and a stopwatch. For years, they stayed ahead of the law by adhering to a generational code of silence and using sophisticated counter-forensic techniques.
