Vacaciones para Ivette (1964)

The Arandas are anxiously awaiting the arrival of a French cultural exchange boy, who will spend a few days with them in Madrid while their son Andrés travels to Paris. However, the little French kid breaks his leg just before starting the trip. Therefore, instead of this child, they send Ivette, his older sister, a very attractive French girl who will revolutionize the family and the entire neighborhood, especially the athletic Miguel, the eldest son of the Arandas.
