Lin Wan, a former well-known jewelry designer, was framed by his first love and business partner Lu Ziqian and sentenced to three years in prison for commercial espionage. Her experience in prison transformed her from a pure and kind-hearted person into a calm and cruel "Black Rose". After being released from prison, she signed a two-year contract marriage with Shen Sihan, the most powerful but terminally ill business tycoon in Jiangcheng, and returned to the upper class as Mrs. Shen to launch a carefully planned revenge. As she gradually revealed the truth, she discovered that the betrayal was far more complicated than she imagined, and the contractual marriage that was meant to be used had quietly deteriorated.
