Description：Fang Lijuan (played by Miriam Yeung) lives a flirting life with Au Haiwen (played by Daniel Wu) every day. While Lijuan is working hard to train herself to be a good daughter-in-law to please her future father-in-law, she accepts another new mission - to protect the princess of a certain country who is about to arrive in Hong Kong. However, she encounters funding problems. Lijuan asks Haiwen for help, which arouses Haiwen's dissatisfaction, and the two have a cold war. Lijuan even thought that the princess seduced Haiwen, and fought with the princess, and was ordered to be suspended. It turned out that the police wanted Lijuan to accept another undercover mission, to go to the country as a socialite to approach Han Yang, the leader of the theft group, and obtain evidence of his crimes. Haiwen followed him to Shanghai, but he and Lijuan both fell into Han Yang's hands. Han Yang threatened Lijuan that he needed to exchange Haiwen for a priceless red wine, and Lijuan, as a police officer, was caught in a dilemma.
