A simple but beautiful animated sequence immerses us in the universe created by director Jimena Monteoliva and screenwriter Diego Fleischer, who, according to the end credits, based the story on a nightmare he had. For years, many girls in a small town have been disappearing. One of them was Elena, who reappears all grown up and is taken by his doctor brother to live with him, his wife and their two daughters. Monteoliva succeeds in creating an atmosphere of constant threat, has confidence in the world she has created and in her characters, and accompanies them until the film’s impressive showdown. Valentina Goldzen and Maitena Dionisi, the two extraordinary girls who play Elena’s nieces, stand out.
