The story is about politics and power struggle among doctors at a hospital.
Friends can switch allegiance and enemies can turn supportive in split seconds. Dr.Jang Joon Hyeok (Kim Myung Min) was an ambitious surgeon who wanted nothing more than to be the department head when his boss retired. His effort was frustrated by his boss Dr. Lee who brought in Dr.Noh Min Guk (Cha In Pyo) from the States with the intention of letting him be the next department head.
Dr. Lee's wife has also set her sight on Dr. Noh to be her future son-in-law whereas the daughter, Lee Yoon Jin (Song Sun Mi) has something else on her mind. Dr. Choi Do Young (Lee Sun Gyun) was a good friend of Dr. Jang and he did not like to get involved in any of hospital's politics but only to concentrate on his work and heal patients. But when Dr. Jang was being sued by a patient's family for causing his death due to negligence, he joined forces with Lee Yoon Jin to stand up for the patient's right at the risk of losing his post at the hospital and friendship.
