It's a family reunion when Dawson (Monica Raymund) and Antonio's (guest star Jon Seda) mother and father come to Chicago for their big anniversary party, but things quickly turn south. When a deep secret comes to the surface involving his stepson James (guest star Juan Lozada), Chief Boden (Eamonn Walker) decides to take matters into his own hands. Meanwhile, Casey (Jesse Spencer) tries to save a young boy during a harrowing call to a warehouse and Otis (Joe Minoso) and Kidd (Miranda Rae Mayo) become competitive at the mud hundred race.

Following the shocking events related to a fallen officer, Teresa and Jarek vow to bring whoever is responsible to justice. In the meantime, Alderman Gibbons pays a visit to the victim’s family to offer his condolences and plant a few seeds of betrayal, implicating members of the Chicago Police Department. As every officer in the city hits the streets to avenge this cop killer, Jarek and Caleb follow up on some of Liam’s leads, while Vonda and Isaac are promoted to the organized-crime task force.
