Moebius

Consumed with hatred against her husband for his long time infidelity, the wife wants to take revenge against him but ends up inflicting a fatal wound to the son, and then disappears overwhelmed with guilt. For the son, who has become miserable because of him, the father tries, only to realize that it is not recoverable, so he cuts off his manhood which is the source of all this misery and dedicates himself entirely to his son. As a result, the wound somewhat heals, but when the wife returns home one day the family is driven towards a more horrific destruction.
