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.
Shi-young picks up Yo Han to bring him to work, but instead he asks her to take him to his doctor: the results are in. The pain medicine team grants Yoo Ri Hye a wish and after some hesitation, she decides she wants to see her son.
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.
