Li Wenjian (Ekin Cheng), a self-confident and capable "VIP Protection Unit" police officer, has a red light on his relationship with his girlfriend Brenda (Lin Jiaxin) due to personality problems. Because of a difficult case, he came into contact with Lai Sheung-ching (Leon Lai), a hypnotist from the former police psychological team who was serving in prison. Although Li Wenjian knew that Lai Sheung-ching was powerful and acted extremely cautious, he was still hypnotized by Lai Sheung-ching without anyone noticing, helping him steal the South African gem that he wanted to protect. In the process of retrieving the gem, Li Wenjian discovered that Lai Sheung-ching had no choice but to steal the gem. He was actually an upright, kind, and humiliating man. He decided to help him fight against the gangster tycoon Ouyang Rui (Francis Ng) who threatened the lives of his wife (Xu Jinglei) and his friend's two children, and in the process he returned to his relationship with Brenda.
