The SVU episode that earned Mariska Hargitay an Emmy for her performance was "911."
The episode is the third installment of season 7 and aired on October 4, 2005. Hargitay plays Detective Olivia Benson, who believes a nine-year-old girl calling for help is trapped in a room, even as other investigators begin to doubt the story. Much of the suspense comes from Benson working the case through a telephone and speakerphone at the station.
Hargitay won the 2006 Primetime Emmy Award for Outstanding Lead Actress in a Drama Series at the 58th Primetime Emmy Awards. The award recognized her performance in this episode, which became one of the most acclaimed installments of the series. It was her first Emmy win for playing Benson.
The episode is often confused with other Hargitay Emmy-nominated episodes, including "Control," "Charisma" and "Florida." Those nominations did not produce the win associated with "911."
