Taxi driver Ermao buys a lottery ticket on behalf of his boss, Zhang, who runs a bar. Unexpectedly, the ticket wins 5 million yuan. Meanwhile, Ermao's wife, Shanshan—upset after an argument—leaves for a tour job in Kanas and casually slips the ticket into Ermao’s red vest. When the greedy Zhang comes looking for the prize, Ermao can’t find the ticket and assumes Shanshan took it. He sets off with his buddy Dacha on a chaotic journey to track her down. In the end, the missing ticket ends up being rolled into a cigarette by an old shepherd.
