An elite team of trauma specialists at a university hospital led by the genius doctor Baek Kang-hyeok.

Baek Gang-Hyeok (Ju Ji-Hoon) is a genius trauma surgeon who has performed surgeries in conflict zones around the world. He is confident in his abilities and has a bulldozer like personality when he thinks he is doing the right thing. He begins to work at a university hospital and leads the severe trauma team there. The severe trauma team is a double edged sword for the university hospital. This is because as the severe trauma team saves more patients, the hospital goes further in in the red financially. Besides Baek Gang-Hyeok, the severe trauma team consists of Yang Jae-Won Choo Yeong-Woo), Nurse Cheon Jang-Mi (Ha-Young) and anesthesiologist resident Park Kyung-Won (Jeong Jae-Kwang). Yang Jae-Won belonged to the proctological surgery department that is led by Professor Han Yoo-Rim (Yoon Kyung-Ho), but Yang Jae-Won was scouted by Baek Gang-Hyeok and joined his team. Yang Jae-Won becomes Baek Gang-Hyeok's first pupil. Baek Gang-Hyeok turns the severe trauma team from a nominal existence to a team that actually goes out into the field and saves lives.—Asian Wiki
