 Yolanda sings in a seedy nightclub. When her boyfriend dies of an overdose, she fears the police and seeks refuge in a convent that saves women from the streets. These off-beat nuns include a heroin using abbess who loves Yolanda, one who writes romance novels under a pseudonym, another raising a tiger in the convent yard, and one who designs fabulous fashions and is in love with the local priest. They plan an evening extravaganza starring Yolanda to celebrate the abbess s birthday and to convince their wealthy patron not to abandon them.
