Desc: El hombre detrás de la máscara: Directed by Gabriela Obregón. The 70th anniversary of the birth of 'El Santo', one of the great legends of Mexican sports, film and culture, and the wrestling debut of his son, mark the beginning of El Hijo del Santo, who takes us into the story, a legacy beyond the ring, and, through personal memories and records, shows us his childhood with a father who had a double identity, and who was always absent from home; and also, the discovery of the hero at home, and his motive for wanting to continue this legacy.
