Harry Brown lives in a desolate council estate, his sickly wife lies dying in a local hospital and he spends most of his days alone, only occasionally venturing out to a local pub to play chess with his best friend. The times have changed in Harry Brown's neighbourhood, drug dealers and gangsters have taken control of the decrepit complex and killings have become a way of life. Overburdened detectives Frampton and Hicock are basically relegated to knocking on doors to inform parents that their children have been killed. But when Leonard is murdered only feet from his own apartment, Harry, a former Royal Marine, uses his military training to take on the violent local thugs.
