Ordinary worker Zhang Yuan and his girlfriend Lin Ya have been in love for five years. To get married, he emptied his parents' savings to scrape together a one-million-yuan betrothal gift, but Lin Ya refused premarital intimacy on the grounds of being conservative. Three days before the wedding, Zhang Yuan was shocked to learn that the betrothal gift had been taken by Lin Ya to buy a million-yuan Porsche for his good brother Li Qiang, and she also tricked him into signing documents intended to defraud him of his property. Driven to desperation, Zhang Yuan sought help from legal genius and law firm boss Su Jin. After gathering evidence, he exposed the conspiracy publicly at the wedding venue, freezing the vehicle and initiating criminal prosecution through legal means. Unreconciled to failure, Lin Ya and Li Qiang successively engaged in malicious litigation, cyberbullying, and even kidnapping and extortion, ultimately ending up in prison for multiple charges including fraud and kidnapping.
