Takeshiro Shikota (Ryo Yoshizawa) is a 27-year-old pediatrician in Hokkaido, Japan. He was born and raised in Hokkaido. One day, Takeshiro Shikota is transferred to the newly established PICU (Pediatric Intensive Care Unit). The unit is for children under the age of 15 who require advance and intensive treatment. There, Takeshiro Shikota meets Dr. Hajime Ueno. Hajime Ueno is a pioneer in his field and hopes to establish PICU all over Japan. He came to Hokkaido from Tokyo to establish PICU, which can use a medical jet plane to cover the vast area of Hokkaido. His goal is to bring sick children to PICU as quickly as possible and accept them under any circumstances. Meeting with Hajime Ueno changes Takeshiro Shikota's life as a pediatrician.—AsianWiki
