A storm at sea opened Cheng Yuanzhou's eyes to people's true nature and showed him the path ahead. After surviving a fall into the sea, he takes his daughter and sets sail again. Starting with each net and every fish, he slowly earns back the life he lost. The ocean has its rising and falling tides, just as life has its ups and downs. As long as there is light in your heart and responsibility on your shoulders, even the hardest road can lead, one step at a time, to a sunny day of your own.
