Greg and Emmett are called to the home of a man at the end of his rope: he's not crazy (he says), but his girlfriend is possessed! They race to the scene with a bible and holy water and...booze for John to drink, since he wants nothing to do with this, but things quickly escalate beyond the boys' control. Can they get out of this? Or is their last hope, truly, at the bottom of a bottle? Tune in for our most dangerous episode yet!
