Road-worn and battle-weary, Kersey (Charles Bronson) longs to leave his fighting days behind him. But when he arrives in New York to visit an old friend, he finds him brutally attacked and gasping for breath in a pool of blood! Now the silent avenger must wage war once more on the city's punks, thugs and hoodlums, but this time he's brought a small arsenal of guns, knives and even a bazooka.
