In the episode of Law & Order: Special Victims Unit titled "911", Olivia Benson is on her way out for the evening when a call comes in from a little girl who says she's all alone. Benson is drawn deeper into the little girl's life, and although the other officers begin to suspect the whole thing may be some sick joke, Benson is convinced that the little girl is the real deal. Through talking to Maria, Benson is able to get enough information to have a place to start, but Maria's captor has been careful with his electronics, making it difficult to find the little girl.

This episode is regarded as one of the best of the entire show, and it's not hard to see why. Even knowing the outcome, the episode is able to keep viewers in distress the entire time. While the writers used a convenient trick of having Maria repeat a rhyme for the officers to have a conversation and then Benson repeating back some phrases to convince Maria she was listening, the episode is still able to keep the suspense high.
