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.
Dinah and the Heart of Gold face destruction at the hands of an undersea leviathan, but music proves to be the key to escape. After a much needed meal, the crew sail on into the maelstrom, making a startling discovery-they've somehow made their way back to the seaport of Anthem, and it appears the lost men of the town have returned home.
