On a southern Qiongzhou island in 1982, Lin Hai is no longer the muddle-headed young man he once was. Facing his hardworking, kind-hearted wife, Shen Yuyin, who has temporarily lost her speech due to illness, he puts aside his youthful arrogance and decides to support their family with his own two hands. Relying on his excellent swimming skills and keen eye, Lin Hai starts by foraging for seafood in the deep waters of Devil's Reef, steadily exploring his way forward and gradually establishing a premium seafood cooperative for the village. The big white goose, Big Cousin, patrols the beach and supervises the work every day, becoming a familiar sight along the shore. There are no earth-shattering business battles, only the changing seasons of the coastal foragers. The couple support each other through thick and thin, leading the entire village to make a prosperous living from the sea and build wealth together.
