After a near-death experience, promiscuous, sexually liberated Cristiana sees the error of her ways and repents on the spot. Having vowed to become a nun to save her sinful soul, Cristiana keeps her word and decides to join a convent, much to the objections of her friends. However, as Cristiana learns the ropes, the fire between her loins starts to burn, and before long, she finds herself relapsing into the same old sins. Can there be forgiveness for Cristiana, the devil nun?
