Slim can't afford to lose another job, so the gas station clerk asks help from his punk-scenester niece, Darla, to exorcise a demon that's taken over his Deming Quick Store. When Darla arrives with only a couple of water guns and a stuttering bookworm, Alex, Slim fears it might be time to pay the piper. But the three arm themselves with holy water and the advice of a mysterious tome: Ghostlore and Deliverance Praxis. Will the unlikely heroes prove capable of this ghostbusting adventure? And can they save ol' Slim's job? His life? Or even his soul?
