Veteran fisherman Lin Shouchuan once saved his older brother's endangered fishing boat, only to be cheated and humiliated instead. Just as his son was injured and his livelihood was in dire straits at home, he resolutely broke ties and left. Using his lifelong skill of reading the sea and tides, he revived Ma Youtian's dying fishing boat, caught a cabin full of rare large yellow croakers in a single net, and finally secured a multi-million-dollar order, winning back his dignity and a way out through skill and trustworthiness.
