Hyper Knife episodes 3 and 4 are out, and the excitement is reaching new heights. Jung Se Ok's character is set to reveal the secrets behind Sol Kyung Gu's character, but what exactly is she hinting at? A murder?

Spoiler Alert!!
Prepare yourself to dive into the captivating world of Hyper Knife, a 2025 medical thriller that is already making waves! Don't worry if you haven't seen it yet; we have all the information you need. This show, which stars the gifted Park Eun Bin and Sol Kyung Gu, has quickly become well-known. We are here to explain the first two episodes that were released on Disney Plus on March 19, 2025.
The narrative centers on two neurosurgeons, Choi Deok Hee (played by Sol Kyung Gu) and Jung Se Ok (played by Park Eun Bin). In an effort to maintain her love for neuroscience, Jung Se Ok, a former rising star in the medical industry, resorts to performing illegal surgeries after losing her license.
Choi Deok Hee, one of the world's top neurosurgeons, once mentored Jung Se Ok, believing in her potential. However, as Jung Se Ok's life unravels, their relationship turns cold, leading to a dangerous and tense situation.
Episode 3 of Hyper Knife brings the drama to a whole new level. Jung Se Ok makes a shocking discovery: the lifeless body of her stalker. This discovery plunges her into a whirlwind of tension and confrontation. Meanwhile, Choi Deok Hee uses his influence to force her into performing a high-risk surgery, pushing her to her limits. When she says no, Choi Deok Hee shuts down her clinic forcefully. This led Jung Se Ok to call him and ask him what he wanted to do. Choi Deok Hee says whatever she wants to confront Jung Se Ok should fly down Busan. Jung Se Ok fights back, leading to a fierce showdown between them. As the investigation into her stalker's death intensifies, the police begin to uncover unsettling truths, adding more fuel to the fire.

In Episode 4, things get even more complicated. Choi Deok Hee visits Jung Se Ok's house, where they have a tense conversation. When asked why she hasn't been at work, Jung Se Ok confesses that she spilled something — only to later admit that she killed in self-defense. She plans to bury the body that night, but Choi Deok Hee questions whether she handled the situation properly.
The police get involved, launching a search team to find the body. In an ironic twist, Jung Se Ok, the suspected killer, is right in front of the police and casually mentions her Rottweiler dog, adding to the eerie tension. But the twist during a heated exchange is that Jung Se Ok accuses Choi Deok Hee of being a murderer as well, vowing to find Myeong Jin Kim's body. She says that when she finds the body, she will give him a call. Choi Deok Hee, however, seems unfazed and drives away. At the end of episode 4 of Hyper Knife, Choi Deok Hee is seen driving the same white car that Myeong Jin Kim drove, leaving viewers wondering what his motives are.
Questions that linger:
- Is Jung Se Ok on a killing spree, and will it restore her lost glory?
- Why is Choi Deok Hee so determined to hide his past?
- What’s driving the growing animosity between Jung Se Ok and Choi Deok Hee?
- Why is Choi Deok Hee trying to protect Jung Se Ok?
As Hyper Knife unfolds, these questions only deepen the mystery and tension between the two main characters. What secrets are they hiding, and how will they each deal with their dark pasts? Only time will tell!
Watch episodes 3 and 4 on Disney+ (JioHotstar in India) and Hulu, which premiere on March 26 at 12:30 p.m. KST (9:00 a.m. IST), to find out what the main characters will do next. After that, new episodes will be released every Wednesday.
