After returning from years of deep-sea fishing, Chen Ye takes out a loan to buy a fishing boat. On the very day the fishing season opens, his own brother, Chen Hai, joins forces with the crew to force him to hand over the boat. Their mother blindly favors her eldest son and demands that Chen Ye sacrifice his own interests for his brother's sake. At his lowest point, Chen Ye awakens a fishing-ground detection system that allows him to locate valuable schools of fish and fight back against the malicious suppression of fishmonger Han Zhen. After enduring one crisis after another, including false accusations and the deliberate sabotage of his boat, Chen Ye draws a clear line between family ties and personal obligations, refusing to compromise his principles. He leads his companions in building a fishing fleet, exposes the mastermind behind the schemes, establishes a successful business, and finds genuine love along the way. At last, he lives life on his own terms.
