One is a judge with a fair name, her name is Zhao Yuanzhu, and the other is a low-level car repairman who works hard every day to repair other people's cars and earn hard money. Her name is Xue Min. But once, the fair and strict Zhao Yuanzhu offended someone. The plan was to frame him, but he didn't expect that the car mechanic Xue Min was also repairing other people's cars at the scene. The car mechanic Xue Min and the judge Zhao Yuanzhu looked exactly the same, and they were both women and it was difficult to tell them apart. So the two people exchanged their identities. What was their fate? What will happen...?
