A creature symbolising rebirth and a fresh new start, the butterly embodies the world of Romina and German, made up of two paralell realities. In one, they grow up as brother and sister, trying to fight their sexual attraction. In the other, they belong to a group of friends where German is with Mariela, whose brother is in love with Bruno who, in turn, is with Romina, who is in love with German. The movie shifts constantly from one reality to the other and carries us to a universe of mixed feelings and genders where everyone will have to find his-her own place. From the director of Plan B and Hawaii.
