One summer evening, two young people meet at the strait. He is Poul and she is Anna. They try to find their rhythm, but it doesn't really work out. In the middle of their experiment, a man appears, Karl. He is suffering from unhappy love and wants to drown himself. Anna and Poul part on bad terms. Poul prevents Karl from carrying out his plan and suggests he try the harbor next time. His unhappy love is named Lykke. She is a dancer at the "Go Go Happy Night" disco, owned by the tough Steffensen.
