After witnessing a domestic dispute, Brett and Violet decide to take the investigation into their own hands. Mouch vets Truck 81’s new firefighter. Herrmann relies on something new to aid him on the job.

A brutal storm rocks Chicago. Will encourages Dr. Grace Song to go against her own findings for the benefit of their patient.

When similar car accidents uncover the fact that someone may be targeting innocent people, a determined Dawson (Monica Raymund) takes matters into her own hands to help push things along. Severide (Taylor Kinney) does everything he can to make Anna (guest star Charlotte Sullivan) feel welcome in her new Chicago surroundings. Herrmann (David Eigenberg), Kidd (Miranda Rae Mayo) and Dawson decide to have Molly's included as a stop in this year's pub crawl, despite strong concerns from Otis (Yuri Sardarov), who may have his own reasons for standing alone. Meanwhile, Casey (Jesse Spencer) tends to his Alderman's duties when a persistent constituent asks for his help in resolving an issue.

Chief Hawkins goes above and beyond to help Brett and Violet with a problem. Kidd pursues an open lieutenant position. A blast from the past asks Mouch and Herrmann for a favor.
