Piraten auf der Pferdeinsel

Horst, a young boy from Berlin, spends his holidays with the "Pirates" at Horse Island. The teen gang is led by Horst′s friend Benno. Soon, Horst realizes that the pirates create a lot of nuisance. Gudrun, whom Horst meets on his way to the village, tells him that she has been attacked and injured by the pirates when she tried to observe a rare cormorant. Gudrun and Horst become friends. Since Benno is less than thrilled about this friendship, he plots a second attack on the girl. This time, however, the other pirates prevent the attack and Benno is forced to come to terms with Gudrun. Eventually, all of them are going to look for the rare bird.
