Two young convent girls become friends and decide to spend the summer together. However, their innocent bicycle rides and walks in the country soon develop a much more sinister side. Influenced by their reading of forbidden books, they decide to explore the world of perversion and cruelty. They find a victim and use their innocent appearance to seduce and destroy him. Once they have stepped over the line, they find it impossible to stop. And soon they are contemplating the ultimate evil act. Hugely controversial, the film was banned for blasphemy and was never released theatrically in the US. This first Blu-ray release is newly restored from the film’s original negative and includes a number of exclusive extra features. The film was screened as part of the Directors Fortnight at the 1971 Cannes Film Festival.
