Chicago Fire (Season 4)

***Chicago Fire* season 4** premiered on October 13, 2015 and concluded on May 17, 2016 on NBC.

For the firefighters, Rescue Squad and paramedics of Chicago Firehouse 51, no occupation is more stressful or dangerous, yet so rewarding and exhilarating. These courageous men and women are among the elite who forge headfirst into danger when everyone else is running the other way and whose actions make the difference between life and death.

The pressure to perform on such a high level has a way of taking a personal toll, sometimes putting team members from the Truck and the specially trained Rescue Squad at odds with each other. Despite any differences, this is an extended family, and when it's "go time," everyone inside Firehouse 51 knows no other way than to lay it all on the line for each other. Lt. Matthew Casey (Jesse Spencer) leads the Truck company, and brash Lt. Kelly Severide (Taylor Kinney) runs the Rescue Squad.

The firehouse also includes Battalion Chief Wallace Boden (Eamonn Walker), a fireman's fireman who is tasked with keeping everything in line and running smoothly between Truck and Squad. Paramedic turned tough-as-nails firefighter Gabriela Dawson (Monica Raymund) returns alongside paramedic Sylvie Brett (Kara Killmer) and seasoned veteran Christopher Herrmann (David Eigenberg). Dora Madison also joins the cast as spunky, spirited paramedic Jessica "Chili" Chilton.

Also returning for the fourth season are Randy "Mouch" McHolland (Christian Stolte), Joe Cruz (Joe Miñoso) and Brian "Otis" Zvonecek (Yuri Sardarov). Jimmy Borrelli (Steven R. McQueen) is the newest addition to Firehouse 51.
