A fledgling mystery writer sees an opportunity to advance her career after the death of a novelist/friend but faces dire consequences when a series of vicious murders occur that seem to implicate her.

A group of family and friends on a camping trip through the Texas badlands are taken on a on-way ride to Hell after they inadvertently witness a ritual sacrifice at a deserted campsite. Pursued by the devil worshiping biker gang responsible, they hole up in an abandoned church near the border, only to discover that they are pawns in a decades-old battle between good and evil.
