The documentary maker discovers how armed officers are dealing with the rising tide of shootings in UK cities, donning a bulletproof vest as he accompanies police on house raids in ordinary suburban streets in Birmingham. Ross also delves into the other side of the law, meeting a gun smuggler who claims the police have lost control of illegal arms importation, gang members who candidly reveal the casual violence of their world, and the mother of a 14-year-old gunned down last year in a gang-related incident.
