S6, E14: Melody Quinn (Mam Smith) is a prostitute who's talking on her cell phone after a busy night. Suddenly, a car approaches and runs her over. When the cops get there, her purse and coat are gone and in addition to being run over, she's been raped and brutally beaten. The 911 call from an uptown payphone gives them clues - the prints of a cop who is part of the Joint Terrorism Task Force. His Lieutenant is hesitant to let the SVU team interview him because he is working undercover, but he finally agrees and it turns out the cop overheard the cell phone conversation that occurred before the hit and run, so he broke cover to call an ambulance. Stabler (Christopher Meloni), meanwhile, has his son Dickie (Jeffrey Scaperrotta) at the precinct, and Dickie says that the crime scene photos look just like a hot new video game that he plays called NtenCity. Sure enough, the murder was a direct copy of the game.
