After five years of marriage, Lin Wan is the public relations director, and her husband Lu Shinian is the youngest vice president of the company. What seems like a perfect marriage is actually full of holes. When she accidentally discovers the ambiguous messages on her husband's cell phone, a war without gunpowder quietly begins. Due to the tit-for-tat confrontation in the conference room, the entanglement of interests in the family business, and the pressure of a third party, Lin Wan decided not to be the meek Mrs. Lu anymore. She wanted to get back what belonged to her - career, dignity, and control of the marriage. However, the closer she gets to the truth, the more she discovers that this marriage itself is a carefully designed game, and is she a chess piece or the chess player?
