In 1940, Masaaki Takaoka (Takashi Sasano)
works as a teacher in the agricultural division at a youth training
institute. All of his students are drafted into the war which is nearing
its end. He makes everyone promise that they will all meet again under
the cherry blossoms upon their safe return. His students soon perish in
the war.
Masaaki Takaoka is wracked with guilt over their deaths. To
comfort the spirits of his dead students, Masaaki Takaoka attempts to
develop a new species of cherry blossoms which can bloom under any
environmental conditions from subtropical to Siberia cold weather (where
his students died).
