Throughout the first seven episodes of this Netflix original, viewers see genius surgeon Baek Kang-hyuk, popularly known as “the hand of God”, being appointed as the new head of the Trauma team at Hankuk National University Hospital in Seoul, South Korea. Initially, when the other specialists of the hospital refuse to trust Kang-hyuk, the Minister of Health and Welfare Kang Myung-hui, who is behind Kang-hyuk’s appointment at Hankuk, assures them that he is “the best of the best”.
Soon, with the exceptional surgical skills he honed during his time in conflict zones worldwide (he served in Syria for eight years), Kang-hyuk earns Hankuk’s respect and leads his team towards becoming the best Trauma unit in South Korea.
In the penultimate seventh episode, Korea’s Hanbit military unit, which is deployed in South Sudan, gets involved in a fight with one of the region’s local militias. In the process, Captain Lee Hyeon-jong is critically shot. With eleven doctors kidnapped by the militia, Hyeon-jong is left untreated in South Sudan. Upon discovering the news, the Minister of Health and Welfare orders Kang-hyuk to immediately leave for Sudan. However, when he reaches Sudan along with his team, Kang-hyuk is stopped from transferring the injured captain to their local hospital for surgery.
In the last episode, Kang-hyuk takes the risk of driving through gunshots to reach the Sudan hospital. However, they are stopped at the main gate. Things take a positive turn when the commander of the militia recognises Kang-hyuk as Malak (he served worldwide under the nickname Malak) and orders the rebels to let him enter the hospital and do as he pleases.
After a crucial surgery, Kang-hyuk and his Trauma team finally save Captain Lee Hyeon-jong and return to Seoul.
Does Kang-hyuk survive the fire?
After the Trauma team arrives in Seoul at night surrounded by reporters, Kang-hyuk learns that there has been a fire and Dr. Han has gone to assist patients on-site. Kang-hyuk rushes to the fire’s location and helps Dr. Han by operating on the injured victims. Soon, a firefighter tells Kang-hyuk that there is a room filled with oxygen tanks and they must immediately evacuate to avoid serious injuries. While everyone rushes out, Kang-hyuk sees a patient stuck there. As he goes to rescue him, an explosion occurs and he’s severely injured.
Barely conscious, Kang-hyuk describes his injuries to team member Jae-won. Following this, the latter moves Kang-hyuk into surgery and eventually saves him.
When Kang-hyuk regains consciousness, he praises Jae-won and calls him by his real name for the first time (for context, Kang-hyuk initially told Jae-won that he will address him with his name the day he earns it).
Is Kang-hyuk able to secure helicopters for the Trauma Center at Hankuk?

Yes, he is. Throughout the Netflix K-drama, viewers learn that Hankuk Hospital’s prime goal is to cut costs and maximize profits. However, Kang-hyuk realises that this directly impacts the trauma team in terms of aid and resources. Though the team manages to save a large number of lives, despite the limited resources, due to Kang-hyuk’s skills and experience, he keeps pestering the Minister of Health and Welfare as well as the Director of Hankuk to supply the Trauma team with its own set of helicopters.
Highlighting the show’s theme of underfunded hospitals, Kang-hyuk reminds the viewers as well as Hankuk’s Directors Choi Jo-eun and Hong Jae-hoon about the importance of using funds for helicopters in trauma centers, which in turn can ensure emergency care for severely injured patients.
Later, Kang-hyuk visits Jo-eun at his home and reveals that he became a doctor because, in the past, Jo-eun had inspired him to be one by operating on his critically ill father, who was turned down by almost every hospital in Seoul. The personal revelation moves Jo-eun and he finally approves using helicopters for the Trauma unit at Hankuk.
At the end of the K-drama, Hankuk recruits more doctors for its Trauma unit. Meanwhile, Kang-hyuk attends an event to inaugurate the Hankuk Trauma unit’s first helicopter. But before the event can conclude, Kang-hyuk receives a call about a rescue unit soldier needing emergency care. Without thinking twice, Kang-hyuk leaves the event with Jae-won and rushes to the location on Hankuk’s newly inaugurated helicopter, while other members of the Trauma unit prepare the OR for the patient.
