“Violet is Blue” is a retro 1970s-style bad-girl revenge-thriller tale of a drug addicted war veteran, Violet Espinoza, whose life consists of getting high and carrying out armed robberies with a motley gang of losers. After Violet does a stint in jail, she learns that her former gang killed her parents for extra drug money. Violet, angered by the police’s non-activity, takes it upon herself to track down her former gang and avenge her parents’ murder one-by-one, in a variety of devious ways; in this dark and twisted romp through suburbia.
