If there’s one television franchise that captures the heart, grit, and humanity of everyday heroes, it’s NBC’s “One Chicago” universe — a powerhouse collection of interconnected dramas from legendary producer Dick Wolf. Often mistaken for a CBS property due to Wolf’s other hit series, the Chicago Fire franchise actually airs exclusively on NBC, where it’s been setting the bar for network drama for more than a decade.

From the firefighters of Firehouse 51 to the doctors of Gaffney Chicago Medical Center and the detectives of the Chicago Police Department, the One Chicago lineup continues to bring fans closer to the city’s bravest responders — and to the pulse of a shared world where courage and chaos collide.

How the “One Chicago” Legacy Began

The story started in 2012 with the debut of Chicago Fire, a fast-paced and emotional series that immediately connected with audiences through its authentic storytelling and deeply human characters. The show’s success ignited what would become a full-blown television universe — the “One Chicago” franchise — expanding to include Chicago P.D., Chicago Med, and briefly, Chicago Justice.

Each series explores a different corner of city life while remaining deeply intertwined with the others. Characters cross paths, storylines overlap, and major crises pull everyone together. It’s a universe built on connection, community, and the shared heartbeat of a city that never stops.

The Core Series of the “One Chicago” Universe

• Chicago Fire (2012–present)
The flagship series that started it all. Chicago Fire follows the firefighters, paramedics, and rescue squad members of Firehouse 51, balancing intense life-or-death calls with emotional personal stories. The show captures both the physical demands of the job and the tight bonds that form between people who risk their lives for one another every day.

• Chicago P.D. (2014–present)
Spinning directly out of Fire, Chicago P.D. shifts the focus to the Intelligence Unit of the Chicago Police Department. Led by the formidable Sergeant Hank Voight, the show dives into the moral complexities of policing in a modern city — where justice isn’t always black and white, and loyalty is everything.

• Chicago Med (2015–present)
A natural extension of the franchise, Chicago Med brings the intensity inside the emergency room of Gaffney Chicago Medical Center. The doctors and nurses confront life-and-death decisions daily, often connecting with patients whose stories link back to cases from P.D. and Fire. The medical drama stands out for its emotional realism and the ethical questions that define modern medicine.

• Chicago Justice (2017)
Though it lasted just one season, Chicago Justice completed the citywide ecosystem, following the prosecutors and investigators of the Cook County State’s Attorney’s Office. Despite its brief run, it added a vital layer of realism to the shared world and deepened the connection between the city’s first responders and its legal system.

Crossover Events and the Power of Shared Storytelling

What truly sets One Chicago apart is its seamless storytelling across multiple shows. Characters frequently appear in each other’s episodes — a firefighter might show up at a crime scene, or a detective might consult a surgeon from Med on a case.

The most ambitious examples are the franchise’s legendary crossover events, which unfold like cinematic blockbusters on television. These multi-show episodes unite all three teams — firefighters, cops, and doctors — to tackle a single city-wide crisis. Past crossovers have dealt with everything from deadly epidemics and high-rise explosions to coordinated terror attacks.

These events not only showcase the scope of the franchise but also remind fans that every department, every character, and every act of bravery in Chicago is part of the same story.

Molly’s – The Heart of “One Chicago”

In a universe full of danger and adrenaline, there’s one familiar refuge for all its heroes: Molly’s, the neighborhood bar that has appeared in nearly every series. Owned by Chicago Fire’s Christopher Herrmann and Gabriela Dawson, Molly’s serves as a crossover hub — a place where firefighters, police officers, and doctors meet to unwind, reflect, and connect.

The bar isn’t just a set; it’s a symbol of the franchise’s unity — a cozy reminder that beyond the chaos, there’s always family, friendship, and shared humanity.

Dick Wolf’s Expanding Television Empire

While One Chicago reigns supreme on NBC, creator Dick Wolf has also built another hit franchise on CBS — the FBI series (FBI, FBI: Most Wanted, and FBI: International). This overlap often leads to confusion among viewers who assume the Chicago shows share the same network home.

In reality, the “One Chicago” universe remains firmly part of NBC’s lineup, with all episodes available for streaming on Peacock and Sunset (https://Sunset-TV.com).

Where to Watch “One Chicago”

You can stream all current Chicago Fire, Chicago P.D., and Chicago Med episodes on Peacock, NBC’s official streaming platform, or catch them on Sunset for on-demand viewing.
