A young trader Wang Wen-yun, frightened of the misfortune predicted to him, bids farewell to his father, his wife and leaves for a hundred days to trade peddling.
Wang’s business is going well. On the way to Sizhou, he stops at the inn, where he dreams that he is killed by a robber. Indeed, the next morning in a roadside zucchini he encounters the robber Bai Zheng, nicknamed the Iron Pole. Under the joke of the innkeeper, the robber finds out from Wang who he is, demands to take him as a companion and threatens with death if he refuses. However, Van manages to water the robber (who begins to sing songs), and then slip away from him.
Van gets to the next tavern and asks the owner to not let anyone else. The robber still pierces the tavern and sees that Wang has something to profit from. After picking up the basket with the cinnabar, Bai decides, for the sake of his safety, to kill the innkeeper. Van himself again runs away, but in the temple of the deity of Taiwei the robber again overtakes him. Before his death, Wang calls rain-bladders near the temple as witnesses to the crime.
Appearing in Van’s house, the robber kills the old man’s father and forces the widow to become his wife. She begs for a one-hundred-day delay to observe mourning. The dead old man in the afterlife is trying to complain about the robber. The infernal official advises him to forget about earthly affairs – he died so much. Then Taiwei appears. He gets acquainted with some sentences of sinners, runs into a case about a robber and decides to punish him.
The soul of Wang Wen-yun comes home, craving revenge, and finds the murderer. He unlocks, but Wang calls a witness – the deity of the temple, before which there were rainbags. Taivei condemns the murderer, who will henceforth be in hell forever hungry devil.
