The mysterious rape of a veteran police officer, who trained Benson, is first linked to her ex-husband's gambling debts, and then to her fellow officers. It turns into a nightmare investigation as the IAB tries to thwart the SVU squad's efforts.

The search for an out-of-state police officer's runaway daughter leads the detectives through an underground rave culture that caters to wayward teens. They use an Internet journalist to track her and their search is seen through the eyes of the squad room personnel as told in their interviews with the Internal Affairs division.
