Set in Middle America, a group of teenagers receive an online invitation for sex, though they soon encounter Abin Cooper, a bloodthirsty preacher, and his family of fundamentalists with much more sinister intentions. What begins as a fantasy takes a dark turn as they come face-to-face with a terrifying "holy" force with a fatal agenda, and soon, the ATF.
