The son, deeply troubled by his father's behavior, tries to convince his mother to leave him and start a new life together. But as she repeatedly refuses, frustration builds within him. Eventually, he decides that if she continues living with his father, he can no longer tolerate their marital relationship. To claim her body exclusively for himself, he shaves her pubic hair and seeks to establish a new, intimate bond with his mother.
