Jung-ju's son died of a heart attack. Since then, she has fallen into endless pain and numb herself by working, drinking, and going to church. One day, Min-gu, a young man who had just been released from prison, came to work at her cleaning company. Min-gu looked ragged and had scars on his face. Jung-ju recognized the young man as the victim who was kidnapped and kidnapped by her and her husband 12 years ago to raise money for their son's surgery. This young man disrupted Jung-ju's life, and she inevitably became curious about Min-gu, just as she felt guilty about him.
