A mischievous snake who assumes human form interferes with the romance between her reptilian sister and a hapless man.

The film is set in five parts, five seasons that are part of the Chinese almanac. The story takes place in the jianghu, the world of the martial arts. Ouyang Feng has lived in the western desert for some years. He left his home in White Camel Mountain when the woman he loved chose to marry his elder brother rather than him. Instead of seeking glory, he ends up as an agent. When people come to him with a wish to eliminate someone who has wronged them, he puts them in touch with a swordsman who can do the job.

Extremely silly comedy about a self-indulgent private investigator who winds up on a cruise ship full of rich patrons, gorgeous women, murderous terrorists, and scarce food.
