After her cousin Zhang Zhiqiang cheated her out of a million yuan in profit-sharing dividends, Lin Xiaohe rescued a three-year-old girl named Duoduo while she was drowning. The girl had the extraordinary ability to understand fish. Lin Xiaohe mortgaged her father's old house and transformed an abandoned quarry into a giant-fish fishing park. With Duoduo's special ability to predict fish activity in advance, she offered a 50,000-yuan reward for catching a big fish, and business soon boomed. Greedy Zhang Zhiqiang resorted to malicious competition and deliberately sabotaged the fishing facilities, only to suffer the consequences of his own actions. Lin Xiaohe recovered the money owed to her, paid off her mortgage, and built a warm and loving home with Duoduo and Duoduo's grandmother.
