A story about the life of General Gyebaek of Baekje in the mid 7th century.

This drama will be about the growth and sufferings of the heart surgeons who work in the thoracic surgery department. Lee Eun Sung graduated from a newly established medical school in the provinces. He applies for a job at the hospital and has high hopes of becoming a great doctor. Nam Hye Suk graduated at top of her medical school. She is an absolute fundamentalist but starts to show her humane side once she gets to know Eun Sung. The problem is Choi Kang Gook just became the new head of the Department of Thoracic and Cardiovascular Surgery. He believes that only doctors can save people's lives and is a genius but he is also a stubborn surgeon who does not care for hospital policies. Only Eun Sung and Hye Suk apply to work in his department.

One day, a famous actor Lee Dong Gwon is admitted into the Hospital for arrhythmia surgery. He immediately falls for Hye Suk, who is his classmate from elementary school. He later gets jealous when he sees that Eun Sung and Hye Suk are getting closer to one another.

Although at first unwillingly, Jo and Gong later become the best of sister/brother-in-law. They depend on each other for help, trouble, and fun. Oh Yuhn Soo, Jo's wife, is grateful at the happy relationship, but things go astray when Gong grows a greater affection for Jo. When Gong confesses her feelings for Jo, the two start to grow apart. Although they later end up in the same police department, they try hard to avoid eachother, and Oh starts to realize the reason why. Kim Rae Won is Gong's friend and the son of a rich hotel owner. Although he knows that Gong likes her brother-in-law, he never gives up his feelings for her. Things seem to turn out alright when Gong starts to date Kim and forget about Jo, but her sister Oh dies. The dangerous yet innocent love for her brother-in-law puts Gong in a terrible situation...how is love different in a family? The beginning of the drama, when Gong is a high school student, is very humorous. The drama is well-written, but if you don't like the unconventional idea of a sister-in-law liking her brother-in-law, you shouldn't watch this drama. Kim Rae Won is portrayed really well, and the character fits him perfectly! worth watching.
