This unique episode features only one of the series' regulars--namely, Lavrne (Penny Marshall). Depressed over recent events in her life, Laverne retreats to a monastery in hopes of getting her head together. Under the watchful eye of the Mother Superior (Fran Ryan), Shirley does her best to fit in with the other pilgrims, tackling duties ranging from pottery-molding to bell-ringing. But our usually loquacious heroine has a lot of trouble--a LOT of trouble--adhering to the monastery's strict vow of silence. Also appearing in this episode is former Mary Hartman, Mary Hartman star Louise Lasser as Sister Margaret.
