Pursued by soldiers, having been accused of heresy, Esteban (Paolo Malco) seeks refuge in a nearby convent - the same convent to which his girlfriend Lucita (Jenny Tamburi) has been banished by her parents. In order to be reunited, Lucita must resist seduction by her lesbian cellmate (Bruna Beani), endure the deranged torments of the Inquisition, and escape from a madhouse
within the convent walls. Esteban, meanwhile, contends with the advances of a sensual abbess (Françoise Prévost).
