La-jiao Zai and Hsiu-fa Juntou are con artists who befriend a family of street venders and entertainers. The group constantly faces financial problems as they are ripped off by thugs, their rent is raised and car breaks down. La-jiao Zai lies, cheats, and steals to come up with the cash that everyone needs. Things get more serious when triad thugs kidnap the daughter of the family, and sell her to a triad boss. The group devises a plan - they decide to dress up La-jiao Zai as a girl and sell her and lovely Hsiao Ying to the gangsters in order to infiltrate the organization and free their friend.
