The Galliano circus has pitched its tents outside the city. The twins, Janet and Kathleen, meet the trapeze artist Jimmy there and fall in love with him. During the first-year class, a window pane breaks. When none of the girls plead guilty, the first class is completely excluded from the circus. But Hanni and Nanni devise a plan to be able to attend the late show. Because all four of them have a present for Jimmy.
