By chance, Qiu (played by Ng Man-tat) and Bee Duofen (played by Sham Kin-fung) met criminal investigation expert Ah Man (played by Hui Koon-man), and the three like-minded people became good friends. However, the real identities of Qiu and Bee Duofen are thieves, and they are incompatible with Ah Man, but Ah Man is unaware of this. The relationship between the three is in a precarious balance. One day, Ah Man ran into his wife Du Baili (played by Hu Yinmeng) dating jewelry tycoon Ah Yang (played by Weng Shijie) in the mall. Ah Man was very angry after being betrayed and decided to retaliate against Ah Yang. Ah Wen drove his motorcycle to compete with Ah Yang's luxury car, but he encountered a car accident. Not only was he injured, but his mount was also scrapped and could no longer be ridden. At the moment of embarrassment, Qiu and Bee Duofen appeared in time to help Ah Wen out.
