Atwater (LaRoyce Hawkins) is settling into his new gig on intelligence as Antonio (Jon Seda) is relegated to desk duty while recovering. Lindsay (Sophia Bush) finally realizes she has no way out and confides in Voight (Jason Beghe) for help. Meanwhile Jin (Archie Kao) is confronted about his secret meetings with Stillwell (guest star Ian Bohen).
As the Sheldon Jin murder investigation moves forward, Voight (Jason Beghe) is under close watch by Internal Affairs but he’s still in complete command of the intelligence unit. A routine undercover job becomes anything but when Voight’s SUV is T-boned while trailing an armored car carrying Ruzek (Patrick Flueger). At District, Burgess (Marina Squerciati) meets her new partner, Sean Roman (Brian Geraghty) and tension is high from the start.
