CineCalidad. Father Julio Lancellotti tells the story of Marino, a transmasculine person who lived in the sixth century, in Lebanon, and who, after his death, was canonized as Santa Marina, considered, by progressive sectors of the Catholic church, the protector of gender identity. With scenes, reflections and interactions of a transmasculine group, the film promotes sensitive contemporary discussions about, for example, respect for the social name, resignifying Santa Marina into São Marino.
