The countdown is nearly over. In just one week, NBC’s powerhouse lineup—Chicago Med, Chicago Fire, and Chicago P.D.—returns with brand-new episodes, and the cast is promising a season full of upheaval, heart, and unexpected twists.

High-Stakes Drama at Chicago Med

The doctors at Gaffney Chicago Medical Center are facing one of their busiest seasons yet. In the exclusive One Chicago: Look Ahead video, Sarah Ramos’ Dr. Lennox takes center stage during a tense trauma case involving multiple burn victims. When another doctor whispers, “She’s gone,” Lennox snaps back: “Not until I say she is!”

Adding to the chaos is Dr. Hannah Asher’s shocking pregnancy reveal. Fans are left to wonder—who is the father? Could it be her ex, Dr. Mitch Ripley (Luke Mitchell), or her colleague Dr. Dean Archer (Steven Weber)? The answer could reshape the ER’s delicate balance.

Meanwhile, Nick Gehlfuss makes his long-awaited return as Dr. Will Halstead, bringing familiar energy to a department already brimming with conflict and compassion.

New Faces and Firestorms on Chicago Fire

Firehouse 51 welcomes rookie firefighter Sal Vasquez (Brandon Larracuente, 13 Reasons Why) into the fold. His first calls include high-octane emergencies—a blazing truck and a series of fast-moving rescues.

Taylor Kinney teases that Vasquez’s arrival will shake things up: “We have some new players, which always creates a ruckus.”

Romance is also in the air. The teaser shows Lt. Kelly Severide (Kinney) sharing a passionate kiss, hinting at new layers in his already complex personal life. Daniel Kyri’s Darren Ritter also returns in Season 14 for a limited run, giving fans one more chance to see a beloved member of the firehouse family in action.

Secrets and Suspicion in Chicago P.D.

The Intelligence Unit is expanding with Eva Imani (Arienne Mandi, The Night) stepping into the squad. But new blood rarely arrives without scrutiny. The veterans quickly start digging into her past, raising questions about loyalty, trust, and what secrets she may be hiding.

Patrick John Flueger (Adam Ruzek) and Marina Squerciati (Kim Burgess) also fuel the romantic intrigue, with sneak peeks suggesting steamy bedroom scenes alongside tense fieldwork.

A Season of Change

While One Chicago will deliver the explosive cases and daring rescues fans expect, this year’s sneak peek proves that change is the true theme of the season. From love triangles and new hires to emotional returns and heartbreaking exits, no corner of Chicago will be left untouched.

As Daniel Kyri wrote in his heartfelt farewell note: “While I know I may never find another cast and crew as amazing as this one, I intend to carry what I’ve learned from you to every set in the future.”
