The film tells the story of Mecha (Graciela Borges), a middle-aged woman in her 50s who has several teenagers and a husband Gregorio (Martín Adjemián), who wants to remain looking young. In order to avoid the hot and humid weather of the city, the family spends the summers in their decaying country estate named La Mandrágora. After Mecha falls and injures herself in the film's opening sequence, she remains confined to her bed, and takes to alcoholism to cope with day-to-day life. She resents dealing with her gloomy Indigenous peoples in Argentina servants, whom she accuses of theft and laziness. Mecha's cousin Tali (Mercedes Morán), who lives in a more modest house in town with her husband Rafael (Daniel Valenzuela), makes repeated visits to the estate with her brood of small, noisy children to escape from her own claustrophobic home environment. Before long, the crowded domestic situation in both homes strains the families' nerves, exposing repressed family mysteries and tensions that threaten to erupt into violence.
