Bouncing back after her failed CW show "The Beautiful Life: TBL," Mischa Barton is trying her hand at some drama on NBC's "Law & Order" franchise.

Barton is a prostitute named Gladys who happens to be the lone survivor out of a string of murdered call girls. Mariska Hargitay's Detective Olivia Benson becomes emotionally invested in Gladys and is forced to make an uncomfortable choice.
