Guy Psycho and the Postmodernaires are broke.

An enigmatic billionaire offers them five million dollars for a private performance of their lounge act. Somehow, that performance includes re-enacting an ancient Assyrian epic deep inside a mountain in Tennessee, in the sub-basement of a mansion that leads all the way to ancient Mesopotamia.

To escape, Guy and his bandmates must retrieve a rumored thirteenth tablet of GILGAMESH. If they don’t, they can’t spend the five million, and worse, they’ll be 5,000 years early for their gig at the Sabre Room.
