A broke man wanders into a bar, drinks himself unconscious, and wakes up at the bottom of the ocean. What follows isn't magical realism wrapped in whimsy, it's a premise that treats its own absurdity with the dead-serious precision of a heist film. The specificity of the setup (10 yen, cheap shochu, a sunken ship) grounds something completely unreal in the texture of actual poverty and desperation, then pivots into something stranger than either premise has any right to be.

A man with no job and no money, too poor even for a cheap glass of shochu, spots a flyer seeking 10-yen investors to salvage a sunken ship. That night he is lured into a bar and drinks until he passes out. He wakes to find himself on the sea floor. There he meets a samurai who distrusts him until learning he is Japanese, and the two join forces to search for treasure. They soon find the wreck of the Mononai-go. The film is a single-episode action story.
