In the early years of the Republic of China, the railway from Shanghai to Chengdu was open. The departure of the first train attracted the attention of the gangsters because it was full of wealthy families, so they colluded with bandits to prepare to rob the train midway. Cheng Qitian (played by Sammo Hung), who specializes in stealing chickens and dogs, also set his sights on this train. In order to get on the train, he decided to blow up a section of the railway in front of his hometown Hanshui Town, and then take the opportunity to get on the train. Unexpectedly, Cheng Qitian was recognized as a wanted criminal by the local security captain Cao Zhuojian (played by Yuen Biao), so he wanted to arrest him. Cheng Qitian luckily escaped the pursuit and successfully blew up the railway. This happened to help the bandits a lot, and they began to besiege Hanshui Town. Seeing that their hometown was about to be destroyed by the bandits, Cheng and Cao decided to unite to fight the powerful enemy.
