New York City factory worker Eddie Marino is a solid citizen and regular guy, until the day a sadistic street gang brutally assaults his wife and murders his child. When a corrupt judge sets the thugs free, he goes berserk and vows revenge.
Vigilante, later released on video as Street Gang, is a 1982 American vigilante film directed by William Lustig and starring Robert Forster and Fred Williamson. Lustig came upon the idea for the film through a news article about "a group of blue collar workers in southern New Jersey who had organized to fight crime in their neighborhood".
