Gu Chengcheng returned to China to inspect the Chengmeng Dance Troupe. During her hidden identity period, she was detained by Xu Fang and others, and witnessed girls like Lin Xiaoya being treated unfairly. Her father, Gu Zhenting, came to rescue her, but was deceived by the person in charge's disguise. After Gu Chengcheng was transferred to the basement, she united other girls to successfully escape for medical treatment. After recovery, she led people back to the dance troupe, revealed her true identity, helped the victimized girls collect evidence, and held the perpetrators accountable. Even under the other party's intimidation and commercial blackmail, the father and daughter still chose to expose all the facts, making the lawbreakers pay the price, helping the victimized girls out of trouble and regaining a new life.
