King (Ekin Cheng) and Queen (Kristy Yang) are siblings. They and Jack (Louis Koo) form a "BadBoy Agent" to find lost love. Taiwan's richest man, Rong Yongxing, wants to find their first love, Asian female sprinter Guan Zheng (Shu Qi). At the same time, the young man Tian Ya (Daniel Chan) also comes to find his missing lover Shadow (Shu Qi). Unexpectedly, Guan Zheng and Shadow have the same face. What's even more unexpected is that King met Eleven (Shu Qi) who had lost her memory in the bar. She is very similar to Guan Zheng and Shadow. The passionate King fell in love with Eleven, and then Eleven was captured. Tian Ya found Shadow. It turned out that the Japanese careerist tried to inject the DNA obtained from Guan Zheng into Shadow's body, but Shadow was disfigured after the failure. After learning about the situation, King and Jack immediately rescued Eleven.
