Philippa Talbot is a talented London businesswoman who has decided to give up her position and power to become a nun. The man who loves her is in shock over her departure from his life. When Philippa arrives at Brede, a cloistered Benedictine monastery, the abbess who was responsible for convincing her to enter this vocation suddenly dies. Her successor is Catherine, a sensitive leader who's the first to tell the newcomer to the community that all nuns are to love without a preference for one over another. This becomes very difficult when Joanna, a young nun, singles Sister Philippa out and grows very attached to her.
