The female police officer Cai Yin (played by Kim Sun-ah) is smart and bold. Due to her task of investigating a gang, she has to return to school and pretend to be a high school student. After being away from school for many years, Cai Yin's knowledge has naturally fallen behind that of others, and she is always cautious to protect herself from being exposed. A girl in her class, the tough leader Hui Ling (played by Hong Su-hee), takes a dislike to Cai Yin and constantly makes things difficult for her. Bound by her undercover identity, Cai Yin can only endure the situation. What makes Cai Yin happy amidst the obstacles is that she has feelings for a classmate named Lu Rong (played by Gong Yoo), but thinking of her true identity and age, she feels dejected. The operation finally makes progress, as the target starts to believe in Cai Yin, and she obtains important clues, but then the situation changes again.
