The One Chicago universe will once again crossover on March 4, 2026 with the NBC shows joining forces for what Oliver Platt calls "topical and current" arc.
"Firehouse 51 is called to an airfield when a passenger jet suddenly goes silent mid-air, triggering a high-stakes emergency. Their discovery cracks open a bigger and deadlier mystery — one with consequences that could ripple far beyond the runway and put countless lives in jeopardy," reads the logline for the three-episode story, which will see Chicago Fire air at 8pm, followed by Chicago Med, and then Chicago PD.

Joking that he had an electric collar connected to his ankle that would shock him if he said too much, Oliver added: "PD figures heavily because an airplane is involved and it's very topical and current."

"On one hand [Dr Charles is] going, 'Hey, maybe the golf leagues are calling,' but that's something that he feels like he's programmed to think because his friends are saying it – I think he really likes what he does," said Oliver of Dr Charles' future.

Dr Charles is an original character on Chicago Med, and Oliver called it "insane" to still be working on the series after 11 years. "But I love working on the show," he shared, calling it "a privilege to get to tell stories that destigmatize mental health issues, and trust me, they still need a lot of destigmatizing."
"It's just remarkable how much voodoo people attach to a mental health issue, but we've all got them in one way or another," he added.

"Our little corner of the internet lit up like a Christmas tree," he said. "The really dangerous thing about a lot of mental health issues is that when they first present, people suffer alone. They don't know that hundreds of millions of people are going through the same thing, and we want to encourage people to reach out."
