| Sister Hanna is a spirited, witty, resolute, warm-hearted, and - attractive nun. With her wit and street cred, she takes charge of Kaltenthal Cloister, transforming it into a popular refuge for all those seeking help of one kind or another. She also brings new life to the sleepy provincial community, proving herself quite a match for her great rival and opponent, the mayor Wolfgang Wöller. |
