Doctor X: Mafia in White, Episodes 1-2: First Impressions

Published: 2026-10-21

A surgeon who refuses staff dinners, ignores rank and never loses a patient walks into a hospital run like a private club. That is the setup of Doctor X: Age of the White Mafia (닥터X: 하얀 마피아의 시대), Kim Ji Won's first drama since Queen of Tears. Here is a spoiler-light look at episodes 1 and 2, based on published recaps, reviews and ratings reports.

Episode 1: the new surgeon says no

Gye Su Jeong (Kim Ji Won) is a freelance surgeon placed by a small doctor-for-hire agency run by Jang Hee Sook (Lee Jung Eun). Before her first day at Guseo University Medical Center she already handles an emergency outside the hospital, with a nervous intern, Park Tae Kyeong (Kim Woo Seok), watching. Once inside, she makes her rules clear: no work outside her contract, no helping seniors with their papers and no bowing to the hierarchy. Her first fight is over an 80-year-old cancer patient. The hospital director wants a big open operation, and Su Jeong argues for a less invasive approach. When the operation goes wrong, she steps in and saves the patient, and the power balance at the top of the hospital shifts.

Episode 2: two patients, one operating schedule

The second episode puts two pancreatic cancer patients side by side: a wealthy company chairman and a teenage girl whose family spent her education savings on treatment. The question of who gets priority, and who gets the best surgeon, turns into a quiet class drama inside the hospital. Senior surgeon Do Yoon Sik (Kim Young Min) struggles in the operating room, and Su Jeong once again ends up doing what others cannot, finishing one surgery and treating the other patient the same day. Short flashbacks to a fire at a medical volunteer group called White Wings hint that she joined this hospital for reasons she is not telling anyone yet.

The cast and the team behind it

Kim Ji Won, known worldwide for Queen of Tears and Descendants of the Sun, plays Su Jeong with a flat, deadpan calm that makes her refusals funny instead of rude. Lee Jung Eun, seen in Parasite, is a highlight as the agency boss who haggles over every clause of the contract. Son Hyun Joo plays Bu Seung Kwon, an ambitious senior doctor who rises fast, and Kim Woo Seok is the curious intern who acts as the viewer's guide. The series is directed by Lee Jung Rim (VIP) and written by Pyeon Seong Geun. It is a Korean remake of the Japanese hit Doctor-X: Surgeon Michiko Daimon (TV Asahi), but you do not need to know the original.

What works (and what does not)

The show knows exactly what it wants to be: a medical noir with dark comedy, where one skilled person exposes how a powerful institution protects itself. The contract negotiations and Su Jeong's blunt honesty give the workplace scenes energy. One English-language review gave the first two episodes 7.5 out of 10, praising Kim Ji Won's timing and the hospital politics. The same review noted the weak spots: senior doctors fail a little too conveniently, the rescues start to feel predictable, and the patients sometimes get less attention than the heroine's skill. If you like case-of-the-week dramas, that formula is part of the fun.

Ratings and Netflix: a strong start

Episode 1 opened with 11.4% nationwide, according to Nielsen Korea figures reported by Soompi and Sports Kyunghyang, the highest premiere of any Korean miniseries in 2026 so far, with a peak of 12.9%. Episode 2 climbed to 14.9% nationwide, according to Sports Kyunghyang. The drama also did well abroad: the Korea Times reported that it ranked No. 1 on Netflix's weekly non-English TV chart in its first week, with 4.6 million views and a place in the top 10 of 36 countries.

Who it is for and where to watch

Give it a try if you enjoy confident heroines, hospital dramas with office politics, or shows like Hospital Playlist but with more bite and less warmth. It has 12 episodes. In Korea it airs on SBS on Fridays and Saturdays at 9:50 p.m. (Korea time). Outside Korea it is on Netflix under the title Doctor X: Mafia in White, with new episodes added weekly after the Korean broadcast. Availability can change by country, so check the catalog in your region.

Our take

A confident, fun start. Doctor X gives Kim Ji Won a cool, sharp-tongued role and builds a hospital full of people worth watching fail. The rescues can feel formulaic, but the jump to 14.9% and the Netflix No. 1 spot show that viewers are hooked.
