A bittersweet comedy about a simple hick who arrives in the big city to seek his fortune, "The Crazy Bumpkins" is about Ah Niu, who leaves his native village to live with an uncle in Hong Kong, not realizing he is a crook. After taking on a hilarious series of illegal jobs with his uncle, he meets and falls for a single mother and decides to find some real work. However, bad luck and naivete soon conspire to keep him from true happiness.

The sequel to John Lo Mar and Chang Yang's original film finds the naive village immigrant, Ah Niu (Yeh Feng) leaving jail to work and live with his crooked Uncle Chou (Wang Sha) again. But now, his girlfriend Ah Hua (Ai Ti) has become the wife of an abusive husband. As with the bittersweet original, Ah Niu -- with his kind heart but simple mind -- gets caught in various rackets and silly situations.
