Shen Yan, who had just given birth to her daughter, was begged by her husband to take the blame and go to prison for her mother-in-law, whose fierce dog injured someone. Lu Chengchuan knelt beside the bed, swearing to take good care of her younger sister and daughter. Three years later, she finished her sentence and left, but what awaited her was her husband and her most trusted best friend, Song Ruyan, getting together, changing her locks, and driving away her three-year-old daughter. Shen Yan did not collapse; armed with sanda skills and the calmness of three years of precipitation, she barged straight into the wedding to confront them on the spot, step by step uncovering the dark secrets of responsibility attribution truth, forged signatures, and seizing the daughter and assets. She retrieved her daughter, reorganized her old subordinates to return to the industry, made those who betrayed her infamous in the face of facts, and lived out a life that did not depend on anyone.
