Law & Order: Special Victims Unit (1999) : 11x17

Detectives Olivia Benson and Eliot Stabler are called in to investigate when a disabled woman, Cara Benson, is beaten and raped. Though the victim's condition has rendered her unable to speak, the detectives soon deduce that someone close to her is responsible, with the lead suspects being her resentful sister and troubled nephew. As the investigation continues, Benson and Stabler strive to make Cara comfortable with coming forward to stand up for herself and illuminating some of the disturbing truths about the assisted living business.
