Fisherman Lu Yuan is betrayed by his partner and kicked into the sea, but miraculously survives. Returning to his fishing village, he starts with a broken boat and uses his fishing skills and business acumen to gradually build a fleet, establish a cold-chain supply system, and create his own brand. He leads the village fishermen in expanding production. Facing market competition and deliberate suppression, Lu Yuan opens up sales channels through a stable supply and reliable quality. Eventually, his business grows larger and larger, and he plans to venture into the open sea.
