Law & Order: Special Victims Unit S07E08 - Starved

When a series of rapes is linked to a speed-dating service, Detective Benson goes undercover and discovers Mike Jergens is the assailant. As the case progresses, Jergens' insecure girlfriend Cora Kennison - an alcoholic and bulimic - becomes an unwilling pawn as both Benson and attorney Minerva Grahame-Bishop seek to persuade Kennison to testify for their respective sides - despite her mother's insistence that her daughter is too fragile. Kennison opts to marry Jergens in the hope that spousal privilege will save her from taking the stand, but since the rapes occurred before they married, she is still forced to testify. Distraught, Kennison drinks to excess, leaving her in an irreversible coma, and her fate in the hands of her husband.
