Lucija, quiet and shy 15-year-old girl, enters the prominent Ljubljana’s Catholic high-school. If she meets her mother’s expectations about the grades, she will be awarded summer holidays at her aunt in Paris – a dream she has been having for years. Never having been practicing music, Lucija is surprised to be invited to join the school’s prominent girls’ chamber choir – a privilege offered to only the most talented first-year students. In the choir, Lucija meets the second year’s most popular and charismatic girl, Ana-Marija. After an intensive singing weekend at the convent, the two become friends.
