Finally, a thriller that can keeps us on our toes! Hyper Knife delves into the underground world of medical science and has the viewer questioning morals and ethics as we follow the journey of a profound neurosurgeon who might be too ambitious for her own good.
Starring Park Eun Bin as Jung Se Ok, a brilliantly talented brain surgeon proclaimed a genius in her field, Hyper Knife is a well-made K-Drama with a captivating story line from start to finish. From the musical scoring to the overall setting and stupendous acting, Hyper Knife feels like 2025’s The Glory as the story is one of revenge and showing no limitations in achieving your goal. Plus, it features another powerful female lead who might have a few screws loose but with good reason.
The story is already a win as it combines a lot of dark sided topics and gloomy undertones that make viewers question morality. Jung Se Ok begged a renowned brain surgeon named Dr. Choi Deok Hee (Sul Kyung Gu) to teach her everything he knew about neuroscience and surgeries. “I don’t want to learn in university, I want everything you know,” she screamed in the rain. Although he seemed reluctant, Dr. Choi sees her fiery ambition and is swayed to teach her. However, want becomes an endearing mentor relationship morphs into a twisted battle of resentment and revenge.
Jung Se Ok performs an unauthorized surgery and is stripped of her license, forcing her to become an underground surgeon performing illegal surgeries for the mafia and black market vendors. While we see Jung saving lives, we question whether she performs surgery out of the kindness of her heart or simply for the satisfactory thrill.
Episode one spares no time in showing us that Jung Se Ok is a loose cannon. Park Eun Bin realistically portrays her character’s maniacal behavior each and every time. From her anger to her despair, Dr. Jung is a rollercoaster of emotions accurately displayed by Park Eun Bin. She kills someone over money, she performs surgeries in the sketchiest of places, she argues with people at an instance and she even goes as far as killing her mentor who she now despises intensely. A game of power, internal politics, and revenge is boiling under the surface and Jung is a walking Pandora’s Box begging to be opened. See just how whacky this character can be in the teaser below.
Although viewers feel compelled to be on Jung Se Ok’s side due to her fascinating and wild behavior, the story prompts viewers to distinguish how she blurs the line between her medical practice, malpractice and to pass our own judgement on the heroine.

The drama’s dark atmosphere and quirky characters are easy to immerse in. The scoring is complementary to every scene and highlights moments of despair, anguish and insanity in a colorful but simplistic manner. Again, similar to The Glory, the visual story telling has an artistic flair that can’t go unnoticed. It is also refreshing to see a drama that is following the hospital genre trend but with a refreshing dark twist. Not only is the doctor rogue-like, similar to The Trauma Code: Heroes on Call lead, but the theme is also more exciting as this doctor hungers for blood- all for her revenge and malpractice. If you’re squeamish, skip past the brain surgery scenes.
While powerhouse Netflix gained enormous success through its various K-Drama genres across the board, Disney may find sweet success in this drama as the story line is captivating and the quality is visibly enjoyable – no budget was spared. While Kim Soo Hyun’s drama Knock Off was Disney’s trump card, Hyper Knife might take the lead. The cast is good and each character plays their part well, but some supporting characters seem to be more unique than the leads at times making you wish they were more present in certain situations. At times, some scenes can feel choppy or lacking some explanation leading up to certain scenarios (particularly episode 1), but it is easy to piece together later on.
Overall, if you are looking for a balanced drama that evokes mental thrills paired with questionable circumstances, Hyper Knife will pique your curiosity and may be your next worthy binge. The drama is a good mix of dialogue and action. There are some medical terms or situations that could be confusing but are easy to follow. The engaging story comes to life as it traverses through Jung Se Ok’s past and leads up to her current insanity and explains her need for revenge. It isn’t groundbreakingly new but a fun watch none the less. Virtually free of romance and melodramatics, this dark drama highlights the tragedy of being too ambitious for your own good. Do your morals align with this radical doctor? (7.5/10)
