My father, who was a truck driver, died in a collision while driving asleep. Reiko is living a poor life with her son with a large amount of compensation. Kato repeatedly visits every month when his wife is killed and demands Reiko's body. However, I was fascinated by Kato, who had a similar situation. One day, the son who witnessed Reiko approaching suddenly begins to rob her mother's body and decides to protect her family.
