Yolanda, a cabaret singer, brings heroin to her lover who drops dead of an overdose. To escape from the police, the singer looks for refuge in a local convent. The Mother Superior, a fan of Yolanda, rapturously greets her. The mission of the order, called the Humiliated Redeemers (Redentoras humilladas), is to offer shelter and redemption to fallen women. The convent once was a bustling haven for prostitutes, drug addicts and murderers, but it is now in disrepair. The order is facing serious financial hardships as their prime financial supporter, the vain and greedy Marchioness (La Marquesa) has decided to discontinue the convent's annuity under the pretense of economizing. The convent had taken in their wayward daughter, Virginia, who subsequently became a nun and ran off to Africa, only to be eaten by cannibals.
