One day, Kotaro (Takeru Shibuya), a 10-year-old boy suffering from severe liver cirrhosis, is admitted to Dojo General Hospital. He has been treated at university hospitals, but none of them can help him. If his condition continues to progress, there is a strong possibility that his liver function will deteriorate and he will die. Sagara (Kazuki Sawamura) proposes a liver transplant operation, but Moriyama (Masanobu Takashima) and his colleagues vehemently oppose it.
