In boxing, the duality between the violence of a confrontation and moving human body in perfect harmony with the mind makes a fight look like a choreographed dance. In this Black and White documentary about the boxer Juliana Rocha, known as Python, it is intended to demonstrate the prospect of a violent sport practiced by a women boxer. Through interviews with the coach and the father we tell her story and motivations. Following one of the matches, we document the magnitude of a sport practiced by woman, in its fullness.
