S01E01 Between Hope and Despair
Second year resident Kang Si Young working as a part-time doctor in prison. Meanwhile, former doctor Cha Yo Han, now a prisoner helps prisoners who are in need of medical treatments.
Seok Ki asks Yo Han how he can understand his patient's pain when he is a CIPA patient who can't feel any pain. Gi Seok opens his eyes, and he can answer Yo Han's question by blinking his eyes. Meanwhile, Eun Jeong exposes Yo Han's secret by writing it on the hospital's bulletin board.
Cha Yo-Han—an arrogant but genius doctor of anesthesiology—and Kang Shi-Young—a smart, warm resident of anesthesiology—work together to help people with mysterious cases of acute or chronic pain.
