Li Chenggong (Xu Zheng (actor)) is a wealthy and arrogant businessman who treats his employees poorly and has a secret mistress, Manni (Li Man). Although his mistress wants him to spend Chinese New Year with her in Shijiazhuang, Li feels obligated to return to his hometown Changsha to celebrate Chinese New Year with his wife Meili (Zuo Xiaoqing), daughter, and mother. Arriving at the crowded airport, Li finds he has been mistakenly booked in the economy class and sits next to the first-time flyer Niu Geng (Wang Baoqiang), a naïve and gullible migrant worker who works as a milk extraction technician. Niu is also setting out to Changsha to claim his defaulted wages from "his boss' debtor" with a (questionable) promissory note given to him by his boss.
