[5] Taking place in the 1760s France, a young girl named Suzanne Simonin is forced by her parents to become a nun.

Due to the maltreatment and physical abuse she undergoes, she is thrown into a world of punishment in which she suffers dehumanization.

The Hollywood Reporter's Jordan Mintzer highlighted that director Nicloux and his co-writer Beaujour breathed new life into the classic story by making the protagonist "much more of a fighting spirit" and by adding a "revised ending".

[6] Variety's Boyd van Hoeij certified the film was "slickly assembled" and frequently provided a "painting-like" cinematography.

[7] Cine Vue's Patrick Gamble judged The Nun suffered from an "inability to deviate from absurdity".
