Dr. Jung Se-ok, a brilliant but disgraced neurosurgeon 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.

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.
