Jessica is a 14-year-old teenager who comes from a marginal background. Her father's abuse since she was little has turned her into an angry self destructive young girl with a great armor even towards her little sister, 8-year-old Alma, with whom she has a relationship of hostility. During a trip to San Juan, Jessica will realize that she doesn’t want to be like her father and she’ll learn to treat her little sister with love and not with violence.
