It was a turbulent era. War, hunger, disease, natural disasters, and the shadow of death shrouded the world, but they could not block the light of dreams and hopes that flashed in my heart. The ordinary Japanese boy Jiro Horikoshi (voiced by Hideaki Anno) was fascinated by the planes cruising in the sky. In his dream, he became friends with Italian aircraft designer Caproni (voiced by Mansai Nomura) and enjoyed the fun of flying. In the terrible Kanto earthquake, Jiro met his lifelong concern-Naihoko Satomi (voiced by Miori Takimoto). After a brief encounter, they missed each other in the disorderly chaos. Under the guidance of fate, Jiro, who was called a genius, became an aircraft designer as he wished. He worked together with his predecessors and peers to rack his brains to improve the performance of the aircraft. The advanced design of Europe made them feel heartbroken, and on the other hand, they were full of contradictions to create a machine that combined dreams and killing attributes. He pursued his dream and reunited with Nahoko. In the turbulent Showa era, the pace never stopped amidst the wind and snow... This film is based on the life story of Zero fighter designer Jiro Horikoshi and the novel of the same name by writer Tatsuo Hori.
