Surgeon Kazuo Okita (Takuya Kimura) has completed his ten-year study and experiment overseas, and returned to the Danjo Memorial Hospital where he once worked, full of experience and enthusiasm. Although he had some unpleasant memories here, he is now more confident and powerful than when he left. Pediatrician Fuyu (Yuko Takeuchi) is the daughter of the dean and Kazuo Okita's former lover, but now she has become the wife of neurosurgeon Tadanobu Asano. For his future and development in the hospital, Tadano became the son-in-law of the dean's family, and eventually took the position of vice dean. The boiling ambition gradually blinded Tadano's eyes and heart. He has been hiding the secrets about Kazuo Okita's past, but at the same time he is also impressed by Kazuo Okita's medical skills and personality.
