The One Chicago universe is gearing up for something big — and according to Taylor Kinney (Chicago Fire’s Kelly Severide) and Marina Squerciati (Chicago P.D.’s Kim Burgess), fans should prepare for an “epic, high-stakes crossover” that pushes every character to the edge.
While details remain tightly guarded, both stars recently teased that the upcoming event is unlike anything One Chicago has done before — and considering the franchise’s history of citywide blackouts, deadly manhunts, hospital lockdowns, and massive explosions, that’s saying a lot.
“It’s Bigger, It’s Riskier, It’s Personal” — What the Stars Are Saying
In a behind-the-scenes interview, Kinney called the crossover “a monster of an episode”, hinting at dangerous rescues, intense fire sequences, and a central threat that forces Firehouse 51 and the Intelligence Unit to team up like never before.
Marina Squerciati added that Burgess finds herself pulled into a case with deep emotional stakes, suggesting this crossover could hit closer to home than fans expect.
According to her, “This isn’t just another joint operation — this one actually changes people.”
A Game-Changer for the One Chicago Timeline?
Producers have been hinting for months that the three shows — Chicago Fire, Chicago P.D., and Chicago Med — are heading toward a story arc that will alter the direction of all three series.
Sources claim the crossover will set up:
-
A new long-term antagonist
-
A multi-episode fallout for P.D.’s Intelligence Unit
-
A shift in Severide’s storyline on Chicago Fire
-
A moral dilemma that splits the teams
If true, this could be the most impactful event since the explosive Season 4–5 crossovers.
What Fans Can Expect
While NBC hasn’t released an official synopsis yet, insiders say the event will feature:
-
High-intensity action across multiple Chicago locations
-
A major casualty or shocking twist
-
A forced alliance between characters who rarely get screentime together
-
A reveal that connects past cases to a new threat
Fans have already begun speculating whether this could tie into ongoing mysteries like Burgess’ past trauma, Ruzek’s undercover history, Severide’s arson investigations, or Voight’s unresolved enemies.
One Chicago Is Pulling Out All the Stops
If Kinney and Squerciati’s excitement is any indication, this crossover is designed to feel cinematic — the kind of event that reminds fans why One Chicago’s interconnected storytelling remains unmatched in network television.
And knowing the franchise’s track record, no character is safe… and no storyline will come out unchanged.
