An historical biography about Jiro Horikoshi, the creator of the Mitsubishi A6M Zero, a fighter plane used by Japan during World War II. Portraying with such delicacy this engineer’s life, as sensitive and a dreamer, means fighting against the rougher contradictions harbored by the human being in a lucid and subtle way. Miyasaky wanted to make us believe it was the final point and its farewell from animation but it was not.
