After ten years as a shut-in, the daughter has grown so violent that her single mother can no longer control her and turns to a rehabilitation institute for help. A male handler moves into their home around the clock, overpowers the rebellious woman with savage force, locks her in a cage, and begins sexually abusing her in the name of treatment. He forces her into deep-throat until she repeatedly vomits, then rams his cock into her dry pussy and pounds her mercilessly. Her defiance gradually collapses into helpless submission. When she finally begs her mother for help, she discovers that her mother has already left. It is too late for regrets: completely broken by the ordeal, she can never return to the life in which she treated her mother like a servant.
