After suffering abuse, Susanna takes refuge in a convent where forbidden love blooms with a clergyman, igniting the wrath of envious sisters who denounce her.

Convent of Sinners is the story of Susanna, a young girl who is raped by her own father and sent to a convent for her sins, where she falls in love with a priest. The other nuns, however, are jealous and angry, they want Susanna for themselves, and accuse her of being possessed by the Devil.—Ørnås
