"Four precepts" was originally a Buddhist term, namely wine, sex, money and anger. The film interprets these four social phenomena in a humorous way. Zhang Hongxue (played by Feng Lei) is a boss who made his fortune in coal mines. As the saying goes, when you are well fed and warm, you will think about sex. On this day, he lied that he bought a house and took a huge sum of money to Hangzhou to meet his lover He Yanfei (played by Jiang Yijia) from the TV station. At the airport, he took Wu Qingsong's (played by Jiang Ke) black taxi. During the chat, Wu Qingsong learned the secret that Zhang Hongxue was carrying a huge sum of money. Wang Dengyun (played by Wang Mengyue), who sells insurance, also got to know Zhang Hongxue because of his sales business and knew that he was a big boss. In this way, the two cunning villains who saw money were thinking about how to get the money. And the lover He Yanfei was also deceived by others to cheat Zhang together, but was killed by mistake. All people fell into the greedy path for money and couldn't extricate themselves, and the final ending began with a sudden car accident...
