Hefty martial arts star Sammo Hung directs this wacky kung-fu-comedy featuring Jackie Chan and Yuen Biao. Jackie Lung (Chan) is a philandering attorney who has been hired by ruthless gangster Hua Hsien-wu (Yuen Wah), who thwarts a lawsuit brought about by the wealthy and angry Miss Yip (Deanie Yip Tak-han). Her complains center around Hua's chemical factory, which she claims is polluting the local drinking water. Hua -- who is making illegal drugs in the factory -- isn't about to give up this lucrative franchise and resorts to all manners of less-than-legal means to defend it. Jackie gets his buddies Wong Fei-hung (Hung) and Tung Tak-biao (Yuen) to convince Miss Yip to sell her fish farm. When Fei-hung moves in next to Miss Yip, he starts to seduce her while Jackie tries to attract Yip's comely lawyer (Pauline Yueng Po-ling). Of course, the scheme falls flat when Jackie and Fei-hung realize that they have actually fallen for their marks while realizing that Hua is a very evil man.
