The story of one of the greatest karate masters of our time, Japanese Taketo Okuda, who was appointed in the 1970s to spread the art of the empty hand fighting in Brazil. From a dauntless warrior to a master in search of transcendence, Okuda’s trajectory is told through the lenses of one of his students, a Brazilian Jewish woman who feels the need of safeguarding. The cultural encounter that follows investigates the deep meaning of martial arts and self-defense in the midst of an increasingly threatening world.
