One hot August evening in the small town of Dodge Junction, Wisconsin, Win and Garth Gasper close their family-owned liquor store for the night.
When the demons Sammael and Jezebeth show up in search of Father Leslie Gardner-the priest that many years ago exorcised Sammael-the Gaspers are forced to confront the most terrifying customers they have ever experienced
Up the hill from the liquor store, Father Gardner senses he is being challenged by the demons. Unable to ignore their foul presence, he makes his way to where the demons have kicked off their destructively sinister plans for the evening.
Now, Garth, Win, Gardner, and three unexpected armed robbers must fight their way out of the liquor store where their flesh and souls are being shredded by the denizens of Hell.
Father Gardner must revisit his terrifying past and renew his faith to defeat the nastiest demon he's ever encountered and protect the lives of his neighbors against the last - and by far the worst - customer of the night.
