Mandatory military service is something every South Korean man has to face, but public health doctors take a different route. Instead of traditional enlistment, they’re assigned to medically underserved regions. For plastic surgeon Do Ji Ui, that assignment turns out to be Pyeongdong Island, a remote place he clearly never wanted to see.
By the end of his first day, he’s already dealing with hallucinations, strange island residents, a medical emergency, and a growing sense that this island might be far more challenging than he expected.
Doctor on the Edge Episode 1 Recap
The episode opens during a military training exercise. While soldiers are practicing wall climbing, two men fall and suffer injuries. One dislocates his shoulder, while the other receives deep cuts.
Do Ji Ui immediately steps in to help. He introduces himself as a public health doctor, explaining that he serves in medically underserved areas instead of completing regular military service.
Back at the medical center, Ji Ui carefully stitches one soldier’s wounds. His precise work impresses both the assistant and the patient. The injured soldier even admits that the experience changes his opinion about public health doctors.
Later, the soldiers discuss future assignments. Ji Ui says he can go anywhere as long as it isn’t an island. One soldier jokes that there are three things to watch out for on islands: accidents, people, and love.
Unfortunately for Ji Ui, fate seems to hear that conversation.
At the ferry terminal, he prepares for his trip while carrying medication. A doctor friend calls and warns him not to take the pills. During the call, another topic involving Hwayeong briefly comes up.
Nearby, a young woman is having a phone conversation that strangely mirrors his own. She casually remarks that scars can be fixed with money and demands compensation from the person on the other end of the line.
Soon, both of them board the ferry bound for Pyeongdong Island.
The trip doesn’t go smoothly. Ji Ui struggles to rest while several older women chat loudly nearby. He seems distracted and mentally distant. Then something alarming happens.
He suddenly sees the same young woman leap into the sea. Without hesitation, he jumps in after her.
Except it never happened. The entire incident appears to have been a hallucination.
The story then shifts to the island’s health center, where staff members discuss the arrival of their new doctor. Before long, Ji Ui wakes up at the clinic, confused about how he got there.
The head nurse introduces him to the facility and begins showing him around. Since he’ll be stationed there for a year, she wants him to get familiar with his new surroundings.
One of the first people he meets is Dr. Yong Jucheon from the Korean Medicine department. Jucheon immediately welcomes him and enthusiastically asks for his phone number so he can add him to multiple group chats dedicated to island life.
Ji Ui is then shown Exam Room Number One, the largest room in the center and now his office.
His excitement quickly disappears.
Most of the equipment is old and outdated. When he asks about replacements, the head nurse explains that requests are submitted every year but rarely receive approval. She also tells him that many patients simply live with chronic conditions because resources are limited.
Ji Ui listens carefully and immediately requests a new blood pressure monitor.
Things get even worse when he moves into his living quarters above the clinic. A centipede lands directly on his face, sending him into a panic. The nurses give him bug spray, and he ends up coating the entire room with it.
The next day, a young man visits the health center regarding home visits. However, Ji Ui refuses to continue making them, pointing out that public health doctors are not required to provide that service.
While unpacking later, he realizes something is wrong.
The suitcase in his room doesn’t belong to him.
Searching for answers, he heads to the village hall and tells the village chief about the mix-up. He also asks whether there was any accident involving a passenger on the ferry.
The chief dismisses the idea immediately. According to him, the ferry has operated for twenty years without a single accident.
He then suggests that the suitcase may belong to the granddaughter of Grandmother Mija. The chief also reveals something surprising: the granddaughter was the person who carried Ji Ui after he lost consciousness.
Armed with vague directions to find “the house with the red rooftop,” Ji Ui begins searching.
Before long, he hears someone yelling for help.
It’s the woman from the ferry.
A dog is chasing her, or so it seems. Ji Ui panics and runs. The woman follows, and moments later the dog simply starts licking her.
A middle-aged woman arrives to retrieve the dog, and both women clearly know each other.
The mysterious woman is finally identified as Ha Ri.
The suitcase exchange happens shortly afterward. When Ha Ri opens her luggage, Ji Ui notices various medical supplies inside. A centipede crawls out, but she calmly puts it back without any concern.
His own suitcase is organized with extreme precision. Ha Ri also returns his medication and advises him not to take it because it doesn’t agree with him.
The conversation eventually turns to the ferry incident. That’s when Ha Ri explains what actually happened. She never jumped into the ocean.
Instead, she had been speaking with Grandmother Mija when her scarf blew away. Ji Ui suddenly attempted to jump into the water, forcing Ha Ri to knock him unconscious to stop him.
Ji Ui is stunned by the story. Although he admits that his memory is incomplete, he remains skeptical and leaves with his belongings.
Elsewhere, Ha Ri and Grandmother Mija prepare food for a memorial ceremony honoring Ha Ri’s parents.
Back at the health center, Ji Ui experiences another awkward moment when he accidentally walks in on a naked man in the bathroom. The man, completely unbothered, introduces himself as Hyeon Chiyeon.
Like everyone else, Chiyeon also brings up the ferry incident. Ji Ui once again insists that he doesn’t remember much.
Later, while unpacking, several photographs fall from his books. The images show Ji Ui standing with a man and a woman in hospital scrubs.
Jucheon soon appears and suggests that Ji Ui treat the staff to a meal since it’s his first day.
The three doctors head to the island’s only restaurant, which happens to be owned by the same woman whose dog chased them earlier.
During dinner, the men discuss their careers.
Ji Ui reveals that he’s a plastic surgeon. Chiyeon says he hasn’t selected a specialty yet and openly admits he has little interest in plastic surgery because he views plastic surgeons as people who primarily chase money.
The comment catches Ji Ui completely off guard.
When the food arrives, things become even more uncomfortable. Ji Ui clearly doesn’t enjoy the meal, but with the restaurant owner standing nearby waiting for feedback, he forces himself to compliment it.
His fake enthusiasm is interrupted by an urgent call from the health center.
A patient needs help.
Ji Ui volunteers to return.
At the clinic, he finds Village Chief Park sitting outside. The older man complains of indigestion and asks for medication.
Ji Ui isn’t convinced.
He insists on conducting a proper examination and quickly realizes that the problem isn’t indigestion at all.
Chief Park is experiencing a heart attack. After administering NTG, the patient’s condition improves rapidly, confirming Ji Ui’s diagnosis. Even then, Chief Park refuses to go to a larger hospital.
Ji Ui explains the seriousness of the situation and warns that he could die if he ignores treatment. While preparations are being made for emergency transport, Chief Park slips away and heads toward his boat.
The situation turns critical when he collapses while lifting a heavy box. Ji Ui rushes in and performs CPR until a helicopter arrives. Both men are transported to Asong Hospital on the mainland, where Chief Park is taken directly into emergency care.
Unfortunately, Ji Ui now faces a new problem.
He’s stranded.
The last ferry has already left.
Following advice from the head nurse, he checks into a motel and spends the night there. He buys instant ramen but falls asleep before eating it.
The next morning, his phone starts ringing nonstop. The health center is overwhelmed with patients, and the staff are furious that he isn’t back yet.
Miss Hwang warns him that abandoning his post carries consequences. One warning is manageable, but a second could prevent him from transferring elsewhere, effectively trapping him on the island for the entire three-year service period.
Panicked, Ji Ui rushes back. Along the way, he experiences flashes of what appears to be a traumatic memory. Before the panic can overwhelm him, Ha Ri places headphones over his ears. The simple gesture calms him immediately.
As he stands there with Ha Ri at the ferry terminal, Ji Ui recalls the warning he received before arriving. Avoid accidents. Avoid people. Avoid love.
In less than twenty-four hours, he has already encountered all three.
And that’s where Episode 1 ends.
Episode 1 Review
I thought this premiere did a great job introducing both the island and the people who live there without rushing through the setup. Rather than throwing constant drama at the audience, the episode spends time showing how uncomfortable and out of place Ji Ui feels from the moment he arrives.
What stood out most to me was the mystery surrounding Ji Ui’s condition. The hallucination on the ferry wasn’t treated as a one-time incident. Combined with the medication, the missing memories, and those brief flashes from his past, it’s clear that he’s carrying emotional baggage that hasn’t been fully explained yet.
Ha Ri also made a strong first impression. Every interaction between her and Ji Ui felt unpredictable, which made their scenes fun to watch. At the same time, there are hints that she may understand more about his situation than she’s letting on.
The medical emergency involving Chief Park was another highlight. It gave Ji Ui an opportunity to prove his competence while also showing the realities of practicing medicine in an isolated community where getting advanced treatment isn’t always easy.
By the end of the episode, I was already curious about Ji Ui’s past, the story behind the photographs in his suitcase, and what exactly happened to the people connected to those memories. The island itself feels like a place full of surprises, and Episode 1 lays a solid foundation for the journey ahead.
