After the big boss Li Chenggong (Xu Zheng) met the milker Niu Geng (Wang Baoqiang), he encountered many problems during his journey. Li Chenggong, who was forced by his lover to return to his hometown in Changsha to confront his wife, encountered Niu Geng, a crow-mouthed man who was going to Changsha to collect debts, at the airport. Niu Geng is as his name suggests, not only honest and simple, but also silly. First, he drank a large can of milk in one breath during the security check before boarding the plane, and then asked the flight attendant to open the window on the plane. It was not easy for him to toss until the plane arrived over Changsha, but he cursed that the plane was forced to return due to heavy snow in Changsha. Li Chenggong, who had no choice but to squeeze into the hard seat compartment of the train, just breathed a sigh of relief, but saw Niu Geng in the crowd again. Niu Geng is like the plague god in Li Chenggong's life. As long as he "opens his mouth", accidents will occur as he said. Due to frequent accidents on the way, the two changed from the train to the bus, and then climbed onto the tractor from the bus. Although Niu Geng's bad mouth made Li Chenggong suffer, this silly young man infected Li Chenggong with his sincerity and optimism. After a bumpy journey, the two finally arrived in Changsha and returned to their respective life tracks. However, the various things they encountered during the journey affected their future lives... This film is produced by Hong Kong veteran filmmaker Wen Jun.
