Hyper Knife

Dr. Jung Se-ok, a brilliant but disgraced neurosurgeon, is haunted by a past tragedy. Stripped of her medical license, she resorts to performing illegal surgeries in the shadows, driven by an insatiable thirst for pushing the boundaries of neuroscience. When her path crosses with her former mentor, the renowned but enigmatic Dr. Choi Deok-hee, old wounds are reopened and a dangerous game of power and revenge ensues. As Se-ok delves deeper into groundbreaking yet ethically questionable procedures, she grapples with the moral consequences of her actions, blurring the lines between medical necessity and personal ambition.
