The sequel to The Crazy Companies sees Kwai (Andy Lau) and his buddies return. Following straight on from the first movie, it starts with the wedding of Horny (Pak-cheung Chan) to his overbearing fiancee Doriana (Sandra Ng).

At the reception we learn that the Kwai's brother is in financial trouble and the company is going to be bought over by Fok's thanks to the meddling of evil executive Robert Cheng. After the takeover, Kwai, Horny, Frank and Kim must get jobs with Fok's and rise up the corporate ladder again before Robert Cheng returns from his 3-month vacation.
