Ludwig (Hansi Kraus) is a mischievous moppet who causes plenty of good-natured fun in this uneven children's comedy taken from the popular book by Ludwig Thoma. He lets loose white mice in the sleeping room of an elderly couple, blows up toys, and replaces his aging Aunt Frieda's (Elisabeth Flickenschildt) beloved parrot with a black cat. Ludwig's mother (Kaethe Braun) and sister (Renate Kasche) must also contend with his hilarious hijinx.
