A friend of Nadia’s (Guest star Stella Maeve) leads the intelligence unit to a huge heroin bust. Unfortunately this bust results in Olinsky (Elias Koteas) arriving home to find the suspects are holding his wife (guest star Melissa Carlson). Voight (Jason Beghe) and the team think they’ve found a common thread with the suspects but it’s not who they think. Meanwhile Burgess (Marina Squerciati) and Roman (Brian Geraghty) are given an assignment where they get paired with a K-9 officer, Jenn Cassidy (guest star Spencer Grammer) who is Roman’s former partner and girlfriend.

The final part of the crossover event finds our intelligence unit joined by detectives from New York’s special victims unit to help solve the pedophile ring case. Ruzek (Patrick Flueger) and Det. Amaro (guest star Danny Pino) along with Halstead (Jesse Lee Soffer) and Antonio (Jon Seda) continue to hunt for the link to foster care and child trafficking. Meanwhile Burgess (Marina Squerciati) and Roman (Brian Geraghty) try to find the shooter from the hospital after using surveillance footage to identify him. Platt (Amy Morton) shows her deep respect for police and the dangerous work they do by honoring their fallen brother.
