After a gang member sexually assaults a young woman, he is pushed from a rooftop in what appears to be an act of retribution. However, when the victim Katie also turns up dead, Benson and Stabler realize that the case is far more complicated than they originally suspected.

Detectives Stabler and Fin investigate the rape and murder of a prostitute who is the victim of a brutal rape. The investigation leads detectives to find that the teenagers were bringing to life the acts included in their favorite video game. The case goes to court, and tension builds as Novak must argue against opposing council Gates' defense that the teenagers were influenced by the violent video game.
