The film explores the theme of the fundamental human goodness and also addresses humorously the issue of rampant thievery on public transport in Mainland China.

Sha Gen ("Dumbo" in the U.S. version, played by Wang Baoqiang), a naïve village boy working as construction worker in Tibet, was returning home to get married.

Refusing to believe that thieves exist in the world, Sha Gen insists on carrying his five years of savings worth ¥60,000 ($8,400 USD[1]) with him rather than use remittance.

Tempted by the huge amount of cash, however, some members disobey and strike, only to be robbed by Wang Bo moments later.

While the two sides tussle, however, a plainclothes police detective (Zhang Hanyu) has been silently watching and awaiting his chance.

This, together with a comparable box office achievement by the Stephen Chow production Kung Fu Hustle, released within the same month, has been hailed as a new milestone for the Chinese film industry.
