Hyper Knife

Once a brilliant neurosurgeon but now a pharmacist in a rural town, Se-ok still performs brain surgeries at night; Se-ok is confronted by Deokhee, the mentor who had a hand in stripping her of her medical license and ruining her life.

Deokhee wants Se-ok to operate on him for a tumour in his head, but Se-ok does not want to comply with her mentor's request; frustrated by his former pupil's reluctance, Deokhee puts pressure on Se-ok.

Before Deokhee's likely tenth Ichida Award win, Seok approaches Mrs. Ichida to steal the trophy.

Seok is in search of Deokhee's vulnerabilities; she is looking for Kim Myeongjin, who drove her and her mentor apart.

Se-ok's past comes back to haunt her when Doo-bong, a former patient, calls and warns her of a threat coming her way; to make matters worse, a sudden house fire pushes Se-ok to the edge.

A rich patient requires a highly complex surgery that needs two skilled neurosurgeons; Deok-hee comes on board, taunting Se-ok and telling her he wants to see what her world is like; stuck with no other choice, the two reunite at the operating table.
