Bellick teams up with Michael, Lincoln and Nika to find Westmoreland's money, and Kellerman continues to target Sara, who receives a surprising phone call.

While responding to a call, Dawson accidentally hits a pedestrian who steps out in front of the ambulance, and must deal with the repercussions.

After the squad is unable to save a woman from a burning building, Severide and Casey disagree on a potential arson case.

Dre encourages the family to support each other, but he falls short of Rainbow's expectations. Zoey and Andre Jr are less than enthusiastic when their parents put them in charge of babysitting the twins.

On Christmas Eve, the team must prevent a catastrophe when torrential rain creates a huge crack in a dam, threatening to wipe out a whole town. Walter's grief finally gets the better of him.

After their last heist was foiled and the team goes underground to avoid repercussions from the authorities, Nate comes out of hiding to directly challenge Blackpoole (the CEO of the company who denied medical treatment for his son) and Sterling (an insurance investigator from the same company). This time, he’s going to steal both of the historic David statuettes right out from under their noses.  But Nate’s bigger challenge is to get his fractured team to work together again. The stakes have never been higher.  Either Nate gets his vengeance, or his friends go to jail for the rest of their lives.
