Three Bad Girls Who Find a Gun and Become Vampires (1970)

In writer/director Christopher R. Mihm's ode to "teensploitation" films of the 1950s and the cinematic oeuvre of the Coen Brothers, three female juvenile delinquents obtain a firearm and, just for the thrill of it, start robbing the fine folks of New Berlin. Unfortunately, their crime spree takes an unexpected turn after they mug and nearly murder the gambling-addicted pastor of the local church—who turns out to be an immortal, blood-sucking creature of the night! Hijinks ensue when the vampiric padre hires a pair of hitmen to help him retrieve his stolen cash and seek revenge against the three bad girls responsible!
