Lucía Puenzo's movie, adapted by the director from her own novel, is a macabre drama-thriller based on a chilling true story. In the beautiful, remote Patagonian landscape in 1960, Eva (Natalia Oriero) and Enzo (Diego Peretti) are taking their children to a small Argentinian town, a community of expatriate and ethnic Germans, intending to reopen Eva's family hotel. They make the acquaintance of a mysterious German doctor (Alex Brendemühl), who is elegant, cultured and charming, but who insists on offering his expertise in genetic medicine in helping with what he considers to be their youngest child's stunted growth – and takes a great interest in the fact that Eva is now pregnant with twins. The doctor seems also to be part of a network helping certain Germans make discreet new postwar lives in South America far from prying European eyes. Soon the horrible truth dawns about this doctor's identity and his ongoing experiments. The film combines the muscular force of a Forsythian thriller with something purely eerie, static and atmospheric. Brendemühl brings a refrigerated menace to his role.
