In the season premiere, 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. Soon she realizes there’s more to his story. After a long day, Lindsay pays a visit to someone she hasn't seen in a very long time -- her mom, Bunny (guest star Markie Post). Jon Seda, Jesse Lee Soffer, Elias Koteas, LaRoyce Hawkins and Amy Morton also star. Stella Maeve, Robert Ray Wisdom and Ian Bowen guest star.

After exercising his disdain and authority over Chief Boden (Eamonn Walker), Chief Anderson (guest star Michael Hanrahan) reassigns members of 51 to various houses around town, citing the need for improvement. The ramifications are felt by the crew, who are left to make the best of their respective situations in their new surroundings. Boden fights to repair the situation, but it just might be out of his control. Elsewhere, Severide (Taylor Kinney) toils over an important decision.
