Colleague Zhang Wei shamelessly borrows Lin Bei's new car for a self-drive trip to Xinjiang, but actually takes his mistress along and brags to others that the car is his own. Lin Bei readily agrees on the surface, but turns around to cancel the ETC, remotely controls the air conditioning and speed alarms to prank him in various ways, and secretly plots to let the evidence of infidelity quietly reach Zhang Wei's wife's ears. In the end, Zhang Wei's affair is thoroughly exposed, he is reprimanded by his father-in-law in person, and ends up divorced with nothing, losing his job, and reaping what he sowed.
