Is set in the town of Bobbio, where Marco Bellocchio, originally from the province of Piacenza himself, spent his holidays as a boy, shot -his feature debut- I pugni in tasca (1965), and set up a film laboratory for young people.
According to Marco Bellocchio, the strangeness of the film is "its defining feature".
The film was born on the back of a chance discovery of the ancient prisons of Bobbio, which inspired the story of Benedetta, a nun walled up alive in the prison-convent of Santa Chiara in Bobbio. It seemed to Marco Bellocchio that this story, unearthed by a past long forgotten, deserved to be brought back to modern-day Italy and more specifically, to a provincial Italy, in Bobbio, which modernity and globalization have wiped out.
Features Marco Bellocchio's daughter Elena, son Pier Giorgio and brother Alberto. When asked about their casting, Bellocchio responded by saying "I couldn't not cast them, it came naturally to me. Your children are the blood of your blood, they're the ones you have to face up to. You live a part of your life with them, you experience hopes and dreams, disappointments and joy together.".
