Where can I watch Corpo Celeste in United Kingdom?

After growing up in Switzerland, 13-year-old Marta returns to a city in southern Italy with her mother and older sister. Independent and inquisitive, she joins a catechism class at a local church. However, the games and religious pop songs she encounters there do not nearly satisfy her interest in faith. Struggling to find her place, Marta pushes the boundaries of the class, the priest, and the church.
