Dixie: Changing Habits (1983)

Arrested for running a house of ill repute, sentenced 90 days house arrest living in a convent, New Orleans madam Dixie Cabot (Suzanne Pleshette) is definitely out of her element. Needing to mend her ways, she learns from the convent nuns, and they learn from Dixie. Cloris Leachman is the Mother Superior who clashes with, and must supervise Dixie, and Geraldine Fitzgerald plays the sage and experienced Sister Agnes.
