Megan and Abby Graves are goth Teen sisters who go on a road trip before Megan heads to New York to make a name for herself in marketing.
They get lost in Arizona and end up in Skull City where they visit a local roadside attraction, Skull City Mine. Soon they discover that the locals are killing visitors and the souls of the dead are being ripped from their bodies and dragged to hell thru a mine shaft that emits a horrible odor.
The town locals come after the girls led by Reverand Abraham (Tony Todd), the girls fight their way free, taking out the locals and at dawn they drive off into the sunrise.
Reverand Abraham is shown being attacked by an invisible menace.
