How has a university hospital been fighting on the frontline against COVID-19? When more and more patients started coming in, the hospital became a battlefield. Following the hospital's wish to leave a record behind, the program director spent 2 months filming with a small camera. Leading the battle was infectious disease specialist Kasahara Kei. Though the hospital was constantly worn by the battle, Kasahara always looked a step ahead. This is a record of those medical professionals, who stood up to fight an unfamiliar virus.
