As her name suggests, You Yongxin is an avid swimmer whose ambition is to make the national team like her father You Shan, the famed "Flying Fish". Her new competitor is the naturally athletic Chen Fei, who has recently returned from abroad. To her shock, Fei is actually her half sister from the same mother. Unfortunately, she becomes involved in a love triangle between herself, Fei, her father's old friend's son Yaoyang and her neighbour Yule. She returns to the pool to forget her sorrows and trains even harder.
