Lieutenant Casey (Jesse Spencer) deals with the fallout of his sister Christie’s (guest star Nicole Forester) impending divorce. Meanwhile, Dawson (Monica Raymund) and Mills (Charlie Barnett) settle into their new roles at Station 51. Elsewhere, Brett (Kara Kilmer) can’t decide if she wants to leave Chicago and the Molly’s crew still can’t figure out how to get the food truck started.

After a bomber blows up a city building, additional targets and innocent people remain in danger. Teresa handles the escalating crisis as Jarek and Caleb race against time to track down the suspect who might have ties to the Chicago Liberation Army. Meanwhile, Alderman Gibbons takes matters into his own hands when an armed teenage robber threatens him, which triggers a reflection on his own youth and upbringing when he was more of an idealist.
