A man, exiled to a coastal village, buys a dilapidated, low-lying thatched hut. Deep in the cellar, he discovers a spring that produces fresh seafood with the tides. He stands up to the oppression of the village bully, breaks the low-price acquisition monopoly of the fish market, builds a live seafood pool to expand his supply channels, and leads the entire village to wealth by making a living from seafood.
