Fisherman Shen Du dreams that, in order to support his adoptive parents' family, he goes out to fish, gets attacked by a shark, and ultimately ends up buried in the sea. Awakening, he comes to a sudden realization, determined to protect his wife and daughter. Relying on his superb fishing skills, Shen joins hands with his brother to go out to sea to make a living, successively neutralizing the malicious schemes of local ruffians and getting acquainted with aquatic products merchants to broaden sales channels. He bravely ventures into dangerous fishing waters several times to capture rare catches, builds up a family business through hard work, and prepares food supplies in advance to cope with the famine years. Breaking free from shackles and steadfastly guarding his original intention to protect his family, Shen Du also leads the fishermen around him to get rich together, completely rewriting his tragic life and welcoming a new life of stability and abundance.
