Once there, she first undergoes degradation to acclimatize her to convent life; then she experiences rampant lesbianism by the repressed nuns, and becomes pregnant by her lover. Finally, her refusal to accede to one nun's lascivious lesbian advances leads to plotting and treachery, and her lover being murdered out of jealousy. Her life now ruined, she further scandalises her family by refusing to take her vows, and leaves the convent, devoting her existence to those in need. Claims to be based on a true story!
