PLOT
Twelve-year-old Joochen lives in a village on the Elbe. He finds a shot beaver and takes it to school with him. The animals are a protected species and he wants the culprit to be found. He also wants to impress the others a little, especially the girl Corina. However, his discovery is met with disinterest and he goes off on his own in search of the culprit. In the process, he makes friends with the hunter "Eule", his future brother-in-law. Joochen finds out that "Eule" has shot the beaver, turns away from him in disgust and reports him to the police. His stubborn behavior does not meet with the approval of the others, because "Owl" did not kill the beaver on purpose. Despite his dislike, Joochen suggests "Owl" as a chaperone for the school trip, but doesn't want to go himself. At the last minute, he decides to go after all and reconcile with "Owl".
