Park Eunbin goes dark in Emmy-nominated ‘Hyper Knife’

Park Eunbin has played brilliant lawyers, devoted royalty, and determined young women. In Hyper Knife, she takes that intelligence somewhere considerably darker.

The Disney+ Korean original, which stars Eunbin as a disgraced neurosurgeon operating outside the law, has been nominated for TV Movie/Mini-Series at the 2026 International Emmy Awards.

The recognition comes more than a year after the series premiered in March 2025, when Hyper Knife introduced audiences to Jeong Seok, a surgeon whose extraordinary talent is matched only by her fixation with medicine.

Seok’s career comes crashing down after her relationship with her mentor, Choi Deokhee, played by Sul Kyunggu, takes a devastating turn. Stripped of her medical license and effectively cut off from the profession she has devoted herself to, she does not walk away from surgery. Instead, she continues operating in secret, taking on patients who exist outside the boundaries of conventional healthcare.

It is a world where Seok’s skill is both her greatest asset and a potential danger.

Then Deokhee comes back into her life.

Once the person who helped shape Seok’s career, he now needs the very surgeon whose future he helped destroy. His request involves an operation that pushes the limits of what can be done, forcing Seok to confront a question that has little to do with medicine: does she use her extraordinary abilities to save him, or finally settle the score?

That conflict gives Hyper Knife its central tension, with the operating room becoming the battleground for two people whose professional relationship has deteriorated into something far more personal.

The role marks a departure from the characters Eunbin has played, which have made her a familiar face to international audiences. Her previous credits include the legal drama Extraordinary Attorney Woo and period series The King’s Affection. As Seok, however, she plays someone whose brilliance does not necessarily come with a conventional moral compass.

Opposite her is Sul Kyunggu, whose credits include Memoir of a Murderer and Oasis. The contrast between the two performers gives the series its complicated mentor-protégé dynamic, with their shared history gradually revealing why their reunion is anything but straightforward.

Written by Kim Sunhee (Quiz From God: Reboot) and directed by Kim Junghyun (After the Rain, My Fellow Citizens!), Hyper Knife combines medical drama with psychological suspense while keeping its central conflict rooted in the fractured relationship between two surgeons.

The International Emmy nomination also puts the series in the company of other Disney+ productions recognized this year, including the United Kingdom’s A Thousand Blows, nominated for Drama Series, and Mexico’s La Peor Vuelta Al Mundo (The Worst Trip Around The World), nominated for Non-Scripted Entertainment.

Hyper Knife offers a very different version of the actor, one driven less by the desire to do the right thing than by an obsession with proving just how far her abilities can take her.

All eight episodes of Hyper Knife are streaming exclusively on Disney+.
