The story is about Lek, a police superintendent, who is determined to get rid of the triad boss Lobster and his gang Sam Tsang, who took Maria from him in the old days. Lek sends Bad Boy, Fattie and Silly Keung to be the undercovers in the gang and promises a huge bonus if they can get them. The three of them do whatever they can to win Sam's confidence. During the operation, they meet Dee, the undercover gangster who worked in the police force, and three gorgeous policewomen, Beau, Fridge and Angel, whom they had a crush on at first sight. However, the three girls think they're gangsters and turn the three guys down. The 3 agents therefore start a hilarious courting mission...
