Good guys aren't always that good, as we've discovered many times over on 'Law & Order: SVU.' And on tonight's new episode, 'Dirty' (10PM ET, NBC), Shohreh Aghdashloo plays a detective who might not be what she seems.
When Saliyah "Sunny" Qadri (Aghdashloo) goes looking for Brooklyn District Attorney Page Ferguson, who might be in danger, the detective arrives just in time to see Ferguson fall from a roof. But during the investigation, Benson (Mariska Hargitay) uncovers Ferguson had a suspicious past -- and that Qadri might be involved, as well.
In this exclusive behind-the-scenes clip, Aghdashloo talks about preparing for the role. Plus, guest actor Doug Drucker shows off his body tattoos, which producers must get cleared before filming.
