Ensnared by the Dark Tunnel on a seemingly endless journey through space and time, the First God Atum, adventurer and test pilot Steve-Steph Alexander, and the foredoomed Silver Knight Barghest travel from realm to realm hoping the next adventure will break the curse and return them home. The trio battle a zombie takeover, fight a conquering sleep demon, clash with Nazis, discover the ghost of Merlin, and stop a lonely queen from destroying the multiverse.
