Chief Pridgen comes under fire after making a tactical error during an apartment fire for which he throws Lt. Casey under the bus, leading Lt. Severide 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, who is faced with the choice of whether to fit in with the firehouse or follow his superiors self-serving orders. Elsewhere, Mouch 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 and a reluctant Cruz take Dawson out on a double date and Boden focuses his efforts on his duties at home as a father.
No job is more stressful, dangerous or exhilarating than those of the Firefighters, Rescue Squad and Paramedics of Chicago Firehouse 51. These are the courageous men and women who forge headfirst into danger when everyone else is running the other way. But the enormous responsibilities of the job also take a personal toll.
With big reputations and hefty egos, the pressure to perform and make split-second decisions is bound to put squad members at odds. When a tragedy claims one of their own, there's plenty of guilt and blame to go around. In the middle of a divorce, Lt. Matthew Casey tries to go about business as usual, but can't help butting heads with the brash Lt. Kelly Severide of the Rescue Squad - and each blames the other for their fallen team member. When it's "go-time", though, they put their differences aside and put everything on the line for each other. This is a look inside one of America's noblest professions.
