After Zhou Xingxing (played by Stephen Chow) successfully completed his campus mission, he thought he could be promoted, but he was transferred to traffic police. Cao Dahua (played by Ng Man-tat), who had made contributions like him, continued to investigate international terrorist organizations in the school as an undercover agent. His career fell into a low point, and even the money for preparing for the wedding was the private money of his girlfriend Amin (played by Zhang Min), which made Axing very helpless. In order to prove his ability, he decided to go to the school as an individual to assist Cao Dahua. The terrorists acted as planned, and the two sides began to fight.
