Natto is a man who specializes in theft, fraud, and other shady activities. One day, he decides to find a stable job but unexpectedly ends up becoming a drug mule. During a drug delivery, he gets into a taxi driven by Lao Xu, a Hong Kong man married to a Taiwanese wife. After a failed business venture, Lao Xu's only means of income is his old, unpopular taxi. Despite their vastly different backgrounds and personalities, these two men embark on a southward journey, accidentally starting a 'delivery' trip. Directed by Chung Mong-hong, the film stars Natto, Michael Hui, Leon Dai, and Tou Chung-hua.
