It's Katrina Harts first day at firehouse 51. Hart Grew up alongside a family of first responders and that's why she grew up to be a paramedic. Katrina is the new PIC ( Paramedic In Charge) after Gabby Dawson left, Katrina already knew Kelly Severide and Stella Kid. Kelly and Katrina went to academy with each other but little does he know his old crush is going to show up and work alongside him. Katrina and Stella met at the first responders gala. Katrina Hart is played by Gabrielle Moses I kept Erin Lindsay in it as I really love her
