Not really. It's more of a fictional creation that borrows some themes and concepts from real religious phenomena but isn't directly based on a specific true story.
The 'Agnes of God' true story is about a young nun, Agnes, who gives birth and claims that the baby was the result of a virgin birth. It delves into the mystery surrounding this event, the investigation into what really happened, and the psychological and religious implications.
The main characters are Agnes, the nun at the center of the mystery, and those who are involved in the investigation, such as the mother superior in the convent and perhaps some medical or psychological experts.
One key element is the nun, Agnes, herself. Her mysterious pregnancy and her claim of virgin conception are central. Another is the Mother Superior who has to deal with the situation within the convent. And the psychiatrist who tries to understand Agnes's mental state is also an important element.
