In this extraordinary Rock'n'Roll/Mythology mashup, Johanna Jones returns to her hometown of Anthem, a down-on-its-luck shipping town, to discover the ship her father sailed on has gone missing. She ends up aboard a yellow submarine named the Heart of Gold, headed directly into Hades' Hexagon to find the missing crew, accompanied by her childhood best friend, a rich young addict, and a punk legend.
The rock 'n' roll/mythology epic continues as past and present traumas of the crew onboard the Heart of Gold are revealed: Johanna discovers a tragic secret about Cherry, Meg's addiction is exposed, and Dinah finds a treasured record from her childhood. All the while, a supernatural ship pursues the Heart of Gold, pushing it deeper into Hades' Hexagon, where the crew encounters a lone stranger floating among wreckage.
