Park Eun-bin bears a grudge against Sol Kyung-gu in Hyper Knife

by solstices

Blood stains the remnants of a broken bond in the main trailer for Disney+’s medical thriller Hyper Knife, starring the talented Park Eun-bin (Castaway Diva) as a brilliant — but deeply disturbed — neurosurgeon who vows vengeance against her former mentor.

Cutting right to the chase, the trailer begins with Jung Se-ok (Park Eun-bin) steps into a makeshift operating theater. “An illegal operation…” muses Sol Kyung-gu (The Whirlwind) as the neurosurgery professor Choi Deok-hee. “How far along is the investigation?” Having once cherished Se-ok as his most promising protége, Deok-hee has since forsaken her, cutting ties over the darkness he perceived within her.

“In a place that’s not even a hospital? And neurosurgery, at that?” scoffs a woman, to which Se-ok merely responds with a wry, lopsided smile. That very night, the woman grins with glee over a hefty wad of cash, only to be accosted with a bag over her head. The next thing she knows, she’s being strangled to death — and then we cut to Se-ok giggling maniacally, a satisfied gleam in her eyes.

Utterly remorseless, Se-ok digs a hole to bury the corpse. Then Yoon Chan-young (High School Return Of A Gangster) — as Seo Young-joo, Se-ok’s bodyguard — finds the dirt-caked shovel. But does Young-joo have it in him to doubt his benefactor, whom he now protects with the life she once saved?

Gazing intently at a preserved brain, Se-ok wonders, “If I follow this path to the end…” To that, Deok-hee answers: “You’ll find humans’ true nature.” But their candid conversations are a thing of the past, because we next see a distraught Se-ok kneeling in the rain as Deok-hee fixes her with a stern glare, having barred her from ever stepping foot into an operating theater ever again.

Years later, Deok-hee seeks Se-ok out again to save his life — “Of course, it’d be best if I did it. But I can’t perform surgery on myself, can I?” Se-ok hasn’t forgotten how he dashed her dreams, pointing out that if her scalpel slips to the wrong nerve… Except Deok-hee’s confident putting his life in her hands, because he knows her pride won’t allow such a mistake, even if deliberate.

That doesn’t mean Se-ok can’t vent her pent-up resentment in other ways, though. Right in front of a collapsed Deok-hee, Se-ok gleefully crushes what looks like Deok-hee’s medicine bottle beneath her foot. Just as the tagline on the poster says, the more one looks at Deok-hee and Se-ok, the more they resemble each other — right down to the way they’re both a tad unhinged.

It seems that apart from Young-joo, there might only be one other person on Se-ok’s side — and that’s Park Byung-eun (The Bequeathed) as the anesthesiologist Han Hyun-ho, who entreats Deok-hee to stop tormenting Se-ok: “She’s going through enough as it is.” But the image of Se-ok splattered with blood during surgery as she saves a patient, juxtaposed against her bloodstained visage after murdering a person, is a spine-chilling one. Everything Se-ok does in the operating theater was taught to her by Deok-hee — but now, as they reunite, Se-ok only has one thing to say to the mentor who betrayed her. “I wish you’d die soon.”

Helmed by PD Kim Jung-hyun (Crazy Love, Awaken) with scripts penned by Kim Sun-hee (God’s Quiz 5), Hyper Knife is slated for a March 19 premiere.
