Intelligent and unassuming 17-year-old Ainara (Blanca Sora) lost her mother at a young age but keeps her close through her faith. When she announces she is considering becoming a cloistered nun, this proposal takes her family by surprise and causes a rift between them, putting relationships and religious conviction to the test. Ainara’s somewhat distant father Iñaki (Miguel Garcés) is preoccupied with a struggling business and his two younger daughters, whereas Maite (Patricia López Arnaiz), Ainara’s atheist aunt, supports her niece’s autonomy but is fervent that the teenager considers university and travel first. Ainara must also consider a blossoming romance with a boy from her choir against the allure of an introspective, peaceful monastic life.
