In a shocking twist, Russo is revealed to be a mole responsible for several security leaks and the hiring of Arthur and Judy Brown, the couple at the center of the local threat.

The case brings Homeland Security Agent John Russo to town. While he initially appears as a friend of Special Agent Meredith Brody , his true motives are far more sinister.

The episode features heavy casualties; Arthur Brown is killed by Pride during a confrontation, and Judy Brown takes her own life while under Russo's manipulative influence. Guest Stars and Production
