“Doctor X: Mafia in White” is a 2026 K-drama, 12 episodes, categorized as Medical drama, Korean noir, Medical Noir, Thriller, and Mystery. It is based on the Japanese TV Asahi drama “Doctor-X: Surgeon Michiko Daimon”. Both are streaming on Netflix.
- Memorable Quote: “A freelance doctor unaffiliated with any medical institution, also known as a mercenary doctor. This story, at its deepest point, is the story of the wolf. A solitary figure who emerged in the era of the mafia in white, in which medicine, where life hangs in the balance, is driven by money and power.”
SUMMARY: A fearless genius surgeon enters a prestigious university hospital riddled with corruption and entrenched power structures, determined to let her skill speak louder than politics. As she takes on impossible medical cases, she exposes the hidden forces controlling the institution while challenging everyone who underestimates her.
♦ MEET Doctor X
In “Doctor X: Mafia in White”, Gye Su-Jeong is a legendary surgeon whose skills are so exceptional that she has earned a reputation as the “mad dog of the operating room.” Unlike many doctors who spend years climbing hospital hierarchies, Gye Su-Jeong is an outsider. She arrives at Guseo University Hospital through a physician-placement agency. She enters an environment where influence, politics, and personal connections often matter more than talent or patient care.
From the moment she walks through the hospital doors, Gye Su-Jeong refuses to conform. Authority figures are challenged. She dares to question unethical decisions and prioritizes patients over power. Gye Su-Jeong believes every patient is a V.I.P. Her confidence and refusal to play by the established rules quickly create dividing lines. Some admire her fearlessness, while others fear her. No doubt about it, her surgical brilliance saves lives. But her independent nature threatens individuals who have long benefited from the institution’s hidden corruption systems. They constantly connive to try to get rid of her.
The People Surrounding Doctor X
- Jang Hui-Suk: The head of the physician-placement agency responsible for bringing her into the hospital. Jang Hui-Suk possesses a sharp business sense and a deeper understanding of the medical world than many realize. The alliance between Gye Su-Jeong and Jang Hui-Suk is both professional and personal. These two women navigate a world where appearances are rarely what they seem.
- Bu Seung-Gwon: The hospital director is attempting to rebuild the institution’s reputation while dealing with internal conflicts and external pressure. His interactions with Gye Su-Jeong create compelling tension. In particular, her actions might expose problems that many would prefer remain secret. He admires her surgical skills but … ______.
- Park Tae-Gyeong: A young intern finds himself drawn into Gye Su-Jeong’s orbit/ He gains a firsthand view of both her extraordinary talent and the realities of a healthcare system struggling with corruption and inequality.
The Operating Room is a Battlefield
In “Doctor X: Mafia in White”, the OR (operating room) becomes a battlefield where decisions can alter lives in seconds. Behind the scenes, power plays are the name of the game, and powerful figures manipulate outcomes for their own gain. Or at least they try. It isn’t so easy when working with someone as unyielding as the notorious Doctor X.
She doesn’t worry about getting terminated, pay cuts, or disciplinary actions. Gye Su-Jeong ensured that the provisions in her hiring contract help her steer clear of unnecessary socializing and predicaments where she’ll have to compromise her ethics and morality. She is fiercely independent and aims to stay that way, avoiding deeply entrenched systems of power.
That’s why she can state plainly to the people who work around her:
“This is exactly the reason I don’t like any of you people. … People who did nothing but study just to make good money and get ahead. You who are only intelligent in the stupidest way, possess no convictions or ethics of your own. You grovel in front of attendings (attending physicians), but hold your heads high in front of patients. … You ignore the corruption above you, but say the system is why you’re corrupt. You only care about your own convenience. … You complacent people, who despite knowing the pointless trauma and suffering the patient will undertake, and that his life is at stake, turn a blind eye – because all you can think is how you can get off easy. … You guys are the lowest of the low”
Clearly, she doesn’t mince words or try to score brownie points.

My personal rating is the same as MDL.
The K-drama “Doctor X: Mafia in White” is everything you would expect in an intense medical drama about a dedicated doctor and doctors who are in it for the prestige and the money. You won’t be disappointed.
Korean TV landscape is crowded with medical dramas, but this adaptation of the popular Japanese drama “Doctor-X: Surgeon Michiko Daimon” transforms a familiar premise (good doctor/bad doctors) into a stylish medical noir packed with tension, mystery, and unforgettable characters. The blending of high-stakes surgery with the dark intrigue of institutional corruption is quite frightening.
