One day, a man, Nonomura (Kazuyuki Asano), is brought to the hospital complaining of severe abdominal pain. At the same time, Shun (Jun Nishiyama), a junior high school student who feels pain in his abdomen, visits the hospital, and Kazue (Ran Ito) diagnoses him with gall bladder infection. The two are placed in the same room, but when Shun's mother learns that Nonomura is homeless, she appeals to have her son moved to another room.
