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.
The condition of MMA fighter Joo Hyung Woo gets worse. He stops breathing, but despite a DNR, Yo Han intubates him. Shi-young hears from Chae Eun-Jeong that the Yo Han's euthanasia patient of three years ago, wanted to live.
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.
