At the 2016 Television Critics Association winter press tour, NBC Entertainment president Jennifer Salke revealed that the network had discussions with Dick Wolf about a fourth series in the franchise centered on the legal system called Chicago Law.

Executive producer Dick Wolf delivers the newest installment of the compelling "Chicago" franchise, an emotional thrill ride through the day-to-day chaos of the city's most explosive hospital and the courageous team of doctors who hold it together. They will tackle unique new cases inspired by topical events, forging fiery relationships in the pulse-pounding pandemonium of the emergency room, and through it all, familiar faces from the Chicago police and fire departments will intertwine as this third team of Chicago heroes hits the ground running.

District 21 of the Chicago Police Department is made up of two distinctly different groups. There are the uniformed cops who patrol the beat and go head to head with the city's street crimes. And there's the Intelligence Unit, the team that combats the city's major offenses - organized crime, drug trafficking, high profile murders and beyond.

No job is more stressful, dangerous or exhilarating than those of the Firefighters, Rescue Squad and Paramedics of Chicago Firehouse 51
