In the film, pop star AKIRA (of EXILE fame) stars as Shiro, a young man who sneaks away from work for 1 hour a day to visit his cancer-stricken father (Eiji Okuda) in the hospital. However, one day he gets the shocking news that he also has cancer, and his life expectancy is actually shorter than his dad’s. Concerned with how devastating this could be to his family and girlfriend (Ayumi Ito), Shiro keeps the news to himself and becomes determined to beat the disease on his own.
