Arne comes into the family of an old friend of his father as a foster child. He hopes to find closeness and security with Harald, his wife Elsa and their children Hans, Wiebke and Lars. But he finds it difficult to integrate - his trust in the community has been shaken by his great misfortune. However, he feels attracted to Wiebke, even though she keeps distancing herself from him. After Arne's clumsiness causes the sailing boat that the young people had restored together to be wrecked during the launch and he is supposedly a traitor after a joint theft, a rift occurs with Wiebke and her brothers. Harald is also deeply disappointed in his foster son.
