Chief Pridgen (guest star Matthew Del Negro) comes under fire after making a tactical error during an apartment fire for which he throws Lt. Casey (Jessie Spencer) under the bus, leading Lt. Severide (Taylor Kinney) to take it upon himself to clear the problem. In an effort to further cover himself from any wrongdoing, Pridgen enlists the help of Lt. Welch (guest star Kenny Johnson), who is faced with the choice of whether to fit in with the firehouse or follow his superiors self-serving orders. Elsewhere, Mouch (Christian Stolte) is floored upon learning that his donation to a fertility clinic has resulted in a child who, now a young adult, wants to meet him. Meanwhile, Brett (Kara Killmer) and a reluctant Cruz (Joe Minoso) take Dawson (Monica Raymund) out on a double date and Boden (Eamonn Walker) focuses his efforts on his duties at home as a father.

In the series premiere episode, Teresa Colvin, the city’s first female superintendent, lobbies for a city corruption task force to investigate Alderman Ronin Gibbons, a building-magnate-turned-politician. Meanwhile, Colvin’s ex-partner and larger-than-life veteran of the Chicago Police Department, Jarek Wysocki, investigates a suspicious murder in Grant Park alongside his new partner Caleb Evers. Also in Jarek’s charge are his niece, Vonda Wysocki; her hotshot partner, Isaac Joiner; and Liam Hennessey, an Irish thug who blends in with the gritty world of local crime. Together, these cops stop at nothing to navigate the Windy City’s underbelly to fight crime and bring down Alderman Gibbons’ empire of corruption.
