Critical: Between Life & Death Season 1- Release date news, cast details, streaming details and more about Netflix’s docuseries

When it comes to high-stakes drama, Netflix is skipping the scripted this time. Critical: Between Life & Death Season 1 is a new medical docuseries that throws viewers right into the controlled chaos of London’s NHS trauma system. And it’s not for the faint of heart—or those who can’t handle seeing just how close life and death really are.

The six-part series, Critical: Between Life & Death Season 1, which premieres globally on July 23, 2025, is set across four major hospitals in London and covers three relentless weeks of frontline emergency response.

Armed with 40 cameras—think bodycams, rigged ER corners, and even surgical suites—the show doesn’t just capture medical procedures; it captures the people behind them, under pressure and often in pain. It’s raw, urgent, and yes, expect it to be very hard to watch at times.

But what truly separates Critical: Between Life & Death from the pack is its access—not just physical access to wards and helicopters, but emotional access to the choices, compromises, and aftermaths of every single decision made when someone’s heart has stopped beating.

The cast: Real lives, real stakes, and one Irish doctor in the spotlight

Critical: Between Life & Death Season 1 stars NHS professionals, patients, and the unpredictable drama of real-time trauma response. One standout is Dr. Marie Healy, an Irish ICU consultant at Royal London Hospital, whose journey from Dublin trainee to critical care director brings an international layer to this very British story. Her presence adds both a personal and national pride moment for Irish viewers tuning in.

The "cast" also includes paramedics from the London Ambulance Service, surgeons from St George’s and King’s College, and air ambulance crews responding by helicopter. And while there are no red-carpet bios, every face you’ll meet here carries the weight of life-altering decisions, captured not with filters or second takes—but in the heat of the moment.

How (and where) to watch Critical: Between Life & Death Season 1?

Critical: Between Life & Death Season 1 will stream exclusively on Netflix, starting July 23. All six episodes will drop on the same day, in true Netflix binge tradition. Whether you choose to consume it all in one emotional gulp or take it slow is up to you—but either way, it’s unlikely you’ll walk away unaffected.

This isn’t a dramatized ER or a stylized Grey’s Anatomy—this is the messy, miraculous, and medically intense reality that millions face but few ever see. And with a creative team that includes the producers of 24 Hours in A&E, expect storytelling that’s both clinical and deeply human.
