Chicago Firehouse 51 is home to noble firefighters and paramedics who look fear in the eye and forge headfirst into dangerous situations in order to help those in need.

These courageous men and women are under pressure to perform at a high level when it's a matter of life and death. Their closeness is like an extended family, but the stress of the job can take its toll on members of the team, putting them at odds with one another. But at the end of the day, everyone is willing to lay it on the line when it counts the most.
