Baek Kang-Hyuk 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 Kang-Hyuk, the severe trauma team consists of Yang Jae-Won, Nurse Cheon Jang-Mi and anesthesiologist resident Park Gyeong-Won. Yang Jae-Won belonged to the proctological surgery department that is led by Professor Han Yu-Rim, but Yang Jae-Won was scouted by Baek Kang-Hyuk and joined his team. Yang Jae-Won becomes Baek Kang-Hyuk’s first pupil. Baek Kang-Hyuk turns the severe trauma team from a nominal existence to a team that actually goes out into the field and saves lives.
