Honestly, walking into the emergency department at Gaffney Chicago Medical Center for the first time felt like a fever dream. If you’ve been following the One Chicago universe for a while, you know that Chicago Med Season 1 Episode 1—officially titled "Derailed"—didn't just start with a polite introduction. It started with a literal train wreck.
Most medical dramas try to ease you in. They introduce the nurses, show you the breakroom, and maybe give you a slow-burn look at a doctor’s morning coffee routine. Not this show. Executive producers Dick Wolf and Matt Olmstead decided to throw us headfirst into a mass casualty event that forced every single character to show their hand within the first ten minutes. It’s chaotic. It’s loud. It’s exactly what Chicago needed to round out the franchise.
The Chaos of "Derailed" Explained
The pilot kicks off with the grand opening of the hospital’s brand-new emergency department. It’s all ribbons and shiny surfaces until a massive elevated train crash sends dozens of critical patients screaming through the doors. This is where we meet Connor Rhodes, played by Colin Donnell.
Connor is a bit of a mystery at first. He’s actually on the train when it crashes, and he starts performing field surgery before he even steps foot in the hospital. Talk about an entrance. When he finally rolls into the ED, he’s covered in blood and barking orders, which immediately rubs Will Halstead (Nick Gehlfuss) the wrong way. The tension between these two becomes a cornerstone of the series. Will is the local guy, the hardworking redhead with a chip on his shoulder, while Connor comes off as the privileged hotshot who just happens to be a surgical genius.
You’ve also got Sharon Goodwin, the Chief of Services, played by the legendary S. Epatha Merkerson. She’s the glue. While the doctors are arguing about chest tubes and ego, she’s navigating the nightmare of hospital politics and the sheer logistics of a collapsed transit system.
Why the Medical Realism Set a New Standard
Medical shows often get a bad rap for being "fake." You see doctors doing things that would get them fired in five minutes in a real hospital. While Chicago Med definitely takes some creative liberties for the sake of drama, the pilot leaned heavily on technical advisors like Andrew Dennis, a real-life trauma surgeon.

Take the case of the surrogate mother. One of the most heartbreaking threads in Chicago Med Season 1 Episode 1 involves a woman who is brain dead but carrying a baby for a couple. It’s a legal and ethical minefield. Dr. Natalie Manning (Torrey DeVitto), who is heavily pregnant herself at the time, has to navigate the horror of keeping a body "alive" just long enough to save the infant. It’s gut-wrenching. It forces the audience to ask: who has the right to decide? The biological parents? The woman’s family? The doctors?
There’s no easy answer. That’s the beauty of this episode. It doesn’t give you a "happily ever after" wrapped in a neat bow. It gives you the messy, grey reality of modern medicine.
Meet the Staff (Before Everything Got Complicated)
Looking back at the pilot from the perspective of later seasons is wild. Everybody is so... green.
- Dr. Daniel Charles: Oliver Platt brings this incredible, calming gravitas to the role of the Head of Psychiatry. In an episode defined by physical trauma, he’s looking at the mental cracks.
- April Sexton: Yaya DaCosta plays the ED nurse who actually keeps the place running. She’s the one who has to tell the doctors when they’re being idiots.
- Sarah Reese: She’s just a med student here. Rachel DiPillo captures that "deer in the headlights" look perfectly. She’s terrified of needles, which, let's be honest, is a hilarious trait for an ER doctor.
The pacing is breathless. The camera moves constantly, mimicking the frantic energy of a Level 1 Trauma Center. You’re not just watching the surgery; you’re feeling the sweat.
The Ethics of the "Red Tag"
In a mass casualty event like the train crash in the pilot, doctors have to perform triage. It’s a brutal system. You tag patients based on their likelihood of survival. Green is walking wounded. Yellow is delayed. Red is immediate. Black is... well, black means you aren't the priority because you're likely not going to make it.

We see the doctors struggling with these choices. It’s one thing to read about triage in a textbook. It’s another thing to look a person in the eye and move on to the next one because you only have one operating room available. Chicago Med Season 1 Episode 1 captures that moral weight better than almost any other pilot in the genre. It sets the tone for the rest of the series: the doctors are talented, but they aren't gods. They fail. A lot.
What Most People Miss About the Pilot
People talk about the train crash, but they forget the subtle character building. Did you notice the tension between Connor Rhodes and his father? It’s a blink-and-you-miss-it moment where we realize Connor isn't just some random traveler; he's part of Chicago royalty, and he hates it.
There's also the introduction of Maggie Lockwood (Marlyne Barrett). She’s the charge nurse, the "desk sergeant" of the ED. In the pilot, her ability to direct traffic amidst the blood and screaming is what keeps the episode from descending into pure noise. She’s the one who knows where every bed is, where every bag of O-negative blood is, and which doctor is about to crack under the pressure.
The One Chicago Connection
We can't talk about "Derailed" without mentioning the cameos. Since this is a Dick Wolf production, we get appearances from Chicago Fire and Chicago P.D. characters. It makes the world feel lived-in. When the victims are pulled from the wreckage, it’s the crew from Firehouse 51 doing the heavy lifting. It reminds you that the hospital is just the final stop in a long chain of survival.
Is It Still Worth Watching?
Absolutely. Even if you've seen the later seasons where characters leave or the plotlines get a bit "soap opera," the pilot stands as a masterclass in tension. It manages to introduce a cast of nearly ten main characters without any of them feeling like cardboard cutouts.

You see Will’s arrogance, Natalie’s empathy, Ethan Choi’s (Brian Tee) disciplined military background, and Sarah’s paralyzing insecurity all within 42 minutes. That’s hard to do.
Key Takeaways for New Viewers
If you’re just starting your binge-watch or revisiting the series, keep these things in mind about the first episode:
- Watch the background. The chaos isn't just for show; the background actors are trained to follow real triage protocols.
- Pay attention to the Rhodes/Halstead dynamic. It defines the first few seasons of the show. It’s not just about medicine; it’s about class and ego.
- The medical cases are often pulled from real headlines. The surrogate mother storyline, for example, mirrors several real-world legal battles over the rights of the unborn versus the rights of the deceased.
To get the most out of your Chicago Med experience, watch the pilot alongside the Chicago Fire episode that preceded it ("2112"). It provides the full context of the train crash and makes the stakes in the ED feel even higher. Once you finish the pilot, pay close attention to Dr. Reese’s journey; her transition from a terrified student to a confident (though often conflicted) physician is one of the best long-term arcs in the show.
Don't just look at the blood and guts—look at the decisions. That’s where the real drama lives.
