In this new historical entertainment, Satoh Takeru and Kamiki Ryunosuke use excavated footage to relive the unknown chains of history. The flapping of a single butterfly's wings triggers a chain of events that becomes a huge storm far away, which is called the "Butterfly Effect". What happened 60 years ago changed Europe and the fate of a young girl in Japan. It is a story of a chain of bravery.
