A zealous, handsome priest, who is the confessor for a convent full of women, encourages the equally zealous abbess of one such institution to enforce the same strict rules on these unfortunate women that are applied to others.

At the same time, a particularly disturbed inmate manages to poison herself and many of the other novitiates in yet another scandal which is covered up by church authorities.
