The documentary examines the themes of religion, youth, and influence through the story of three girls who killed a nun. It has a voiceover narration and uses a linear structure to tell the story from beginning to end, including the investigation and conclusion. Various camera techniques were used, including talking head interviews following the rule of thirds. Religious symbols were featured as a binary opposition to examine the theme of religion. Sound effects like church bells were incorporated alongside translations of Italian interviews. Archive materials such as police reports and newspapers were also included with narration.
