Ulf would do anything to win Biggi's heart. Because he wants to impress her, he decides to join the sailing club. Despite the mockery of his friends, he is not dissuaded from his plan and spares no effort to make an impression on his beloved. But she only gives him the cold shoulder, whereupon he manipulates her boat. As a result, Biggi ends up in last place in an important regatta race. Both are threatened with expulsion, which is why they have to pull themselves together.
