Maddalena (Lisa Gastoni) is a young sensual woman, with a tormented soul. Separated from her husband, who won't grant her a divorce, she desperately seeks true and sincere love. During one of her erotic parties, she meets a young priest (Eric Woofe), dragged in front of her for a bet. Maddalena sees in that priest, doubtful about his ability to cope with his oath of celibacy, her own spiritual and physical salvation. She therefore decides to become a constant presence in his life and to seduce him.
