In the early years of the Republic of China, the railway from Shanghai to Chengdu was opened. The departure of the first train attracted the attention of the gangs, because it was full of wealthy families, so they colluded with mountain thieves to prepare for carjacking. Cheng Qitian, who specializes in sneaking around (Sammo Hung), also got the idea of this train. in order to touch the train, he decided to blow up a section of railway in front of his hometown Hanshui town and then get on the train. Unexpectedly, Cheng Qitian was recognized by Cao Zhuojian (Yuan Biao), the local security chief, as a wanted criminal, so he wanted to arrest him. Cheng Qitian narrowly escaped capture and successfully blew up the railway. This was a great help to the mountain thieves, and they began to besiege Hanshui town. Seeing that their hometown was about to be destroyed by mountain thieves, Cheng and Cao decided to unite against the strong enemy.
