“Mayhem in 1982 is rooted in the true story of Long Island’s most infamous crime spree. On Friday night, Memorial Day weekend in 1982, five Brooklyn thugs, known as the Belmont Avenue Boys, went to “get paid” on Long Island, or as they called it, Babylonia, the biblical land of milk and honey. Their creed—“if you want something, just take it-“was demonstrated by the night’s work of random shootings, rapes, sodomies , pistol whippings, robberies, and terrorism by forcing diner patrons to “undress and have sex with the person next to you.” In an ultimate act of vulgarity, the Boys then urinated on several of the victims. Following their arrest and sentences of 3.000 years in prison, the outraged public learned of a defect in NY Sate law , trimming the sentences to thirty years.

Thirty years later, in 2012, as news of the Boys release, circulates, a product of one of the rapes discovers the truth of his conception, and vows to avenge his mother’s degradation. Concocting a plan to snuff out the lives of the Boys, including his rapacious father, he recruits several victims of that night of terror, and he lures the Boys to a secluded warehouse, where appropriate justice is finally served.
