Kara Killmer joins the cast this season as Sylvie Brett, a fresh-faced young paramedic who has transferred to Firehouse 51 from a rural fire department in Indiana after the sudden breakup of her engagement. Her sunny, unflappable personality will be challenged as she starts over, separated for the first time from her small-town roots while assimilating to life as a first responder on the tough streets of Chicago.
