In a sleepy village in the Basque Country, a sculptor named Ane and her three children arrive at her mother Lita's home for summer vacation, where they are surrounded by extended family and nosy neighbors. Ane and her mother's relationship is strained — Lita disapproves of her daughter's frayed marriage, career, and the way she parents her obstinate, mischievous children. Chief among them is eight-year-old Aitor, nicknamed Coco after it becomes clear that being referred to by their birth name elicits feelings of distress in the child.
