Trapped in an elevator while transferring a patient to the operating theater, Jin Hee and Chang Min are forced to perform a tracheotomy on the patient without supervision. While the other interns are in awe of Chang Min, who they thought had performed the procedure, Chief Gook discovers that Jin Hee was the one who did it. Meanwhile, Chang Min and his mother find out that the blind date who stood him up was fellow intern, Han Ah Reum.

The doctors convene an emergency meeting to investigate the identity of the ER intern who had performed the tracheotomy on a esophageal cancer patient who is now dead and whether the operation contributed to his death. Chang Min's mother is admitted to the hospital as a VIP patient and is surprised to find out that Jin Hee is an intern working alongside her son.

Chang Min's mother demands that Jin Hee be replaced by Han Ah Reum as her doctor. Confronted by animosity from Chang Min's mother and her possible dismissal, Jin Hee decides to resign. However, after seeing Jin Hee taking the initiative to help an outgoing patient to get treatment, Chief Gook rejects her resignation and encourages her to continue her internship.
