In a small coastal fishing village, Zhou Haisheng, a poor fisherman, enters Lin Wanqing's home through a matchmaking arrangement. After her father disappears at sea and creditors arrive demanding repayment, the two sisters are left with nothing but a dilapidated, leaking boat. Using his skills in boat repair and fishing, Haisheng joins forces with Wanqing and Xiaoman. Together, they gradually pay off their debts and build a livelihood, selling fresh fish, catching green crabs, and transporting live lobsters. Facing competition for profits and the dangers of the sea, he remains committed to honest business and sustainable fishing. Putting past grievances aside, he rescues his neighbors in need and helps his family find Lin's father, who is stranded on an isolated island. The broken boat carries more than just a means of survival; it carries the hope of ordinary people pursuing happiness through hard work, courage, and responsibility.
