His employer thinks he's dotty, and refuses to fund any crazy idea. He returns home to his apartment and finds a woman there. She takes him to Preston B. Whitmore, an old friend of his Grandfathers. He gives him the shepherd's journal, a submarine, and a 5-star crew. They travel through the Atlantic Ocean, face a large lobster called the Leviathan, and finally get to Atlantis. But does the Atlantis crew have a lust for discovery, or something else?
