Li Yuan, a lawyer's assistant, discovers on the night before her wedding that her fiancé, Zhou Ming, has plagiarized the intellectual property manuscript she wrote five years ago. She keeps her composure and secretly spends three months laying the groundwork for her plan. On the wedding day, she publicly replaces the wedding invitations with court summonses and sues Zhou Ming and law firm partner Zhang Da. She subsequently faces contract termination, an industry-wide blacklist, and financial hardship. However, with the help of her allies, she gathers irrefutable evidence. Ultimately, in court, she exposes the truth with a complete chain of evidence and makes the infringers pay for their actions.
