Su Ning, a fishing village girl from Dulan Bay, faced a crisis when her father lost contact out at sea, leaving her family heavily in debt and their fishing boat nearly seized. Gu Chuan, a boat-repair youth, stepped forward to help the Su family secure their livelihood. Through wind and rain, the two came to know and support each other, shouldering the heavy burdens of the family together. They ventured out to sea for fishing and beachcombing, resisted the harassment of the merchant Wei Cheng, and guarded the baseline of marine fishing. Having endured numerous hardships including perils in searching for family, violent storms, and the destruction and rebuilding of their boat, everyone looked out for one another and finally found Su Ning's father. The small boat was renamed "Homecoming," and the family turned from bitterness to sweetness, welcoming new life by the vast sea and upholding a warm, vibrant home with diligence and kindness.
