Bai Mu's son died in a car accident. Bai Mu's spirit was severely stimulated. She blamed herself for her son's death, and far-fetchedly blamed the proprietress of a small restaurant with whom she had a dispute on the day of the accident, and the little boy who played in water with her son. The driver who caused the accident, Jiang Bei, originally escaped after the car accident, but because of self-blame, he found Bai Mu in the hospital and took her home. Bai Mu recognized Jiang Bei and determined to take revenge. He pretended to be crazy in daily life, tried every means to strengthen Jiang Bei's self-blame, used self-mutilation and other methods to cause psychological torture to Jiang Bei, and finally led Jiang Bei to kill the proprietress of the small restaurant and the little boy. After Jiang Bei was arrested by the police, Bai Mu returned to his normal appearance, returned home and killed his affair husband. After liquidating all the "sinners", he jumped from the overpass and committed suicide.
Intention: Perhaps the biggest sin in the world is not letting yourself go.
