Kidd and Severide's honeymoon is interrupted by a dangerous person from their past; Kidd's former academy classmate joins Firehouse 51; Brett and Violet reflect on their relationships.

Chief Boden leads the fight to keep the firehouse open, an emergency call to an apartment structure puts the squad in harm's way, and Dawson receives life-changing news.

The shooting of a child in their neighbourhood forces Cruz and his brother to think about the gang, Isabella gets Mills to dress up for a gala, Casey feels sad he will be seeing Dawson less, and Shay gets in deeper with Devon.

Severide comes across a boy in need of help while out on a jog. Boden and McLeod clash over the future of the firehouse. Mouch and Greg Sullivan debate on Otis' podcast.
