Park Yeong Hui comes from a family which has been working in the police for generations. To stay traditional, she joins the service. On the other side is Han Cheol Su, who has inherited a vast fortune from his parents. After the two of them meet by accident, they fall in love and decide to marry. Both families are strongly opposed to the planned marriage, leading Cheol Su to decide to join the police academy, although it turns out to be not a half as easy as he has thought.
