Nine-year-old Franz Fröstl goes to school in Vienna. He is the smallest in his class. When he gets angry, he lets out a high-pitched, shrill voice that he loses in front of the strict teacher Zigzag. Franz is therefore teased regularly and his parents are not much help in this respect either. His best friends are Gabi and Eberhard, Franz can fully rely on them. In search of strength and self-confidence, Franz finds videos on the Internet by the influencer Hank Haberer, who gives advice on how to become 'real men'. Gabi and Eberhard are not very enthusiastic about this and the friendship of the three is put to the test.
