It's no big secret that twelve-year-old Hannes is in love with his classmate Carolin, who he compares to a beautiful white cloud in the sky. But when Carolin spends most of her time exploring the village's history with Benno, Hannes becomes increasingly jealous of his rival. The only person who is happy about this situation is Kerstin, who is in fact interested in Hannes. In order to impress Carolin, Hannes takes her and several others out for a boat ride in the nearby Bay of Greifswald, but his plan takes a deadly turn as a storm approaches.

Josef Neumann has always been an outsider to society, and at the age of 30, he has already lived an adventurous life when he comes to the GDR. He was raised as a foundling by nuns, made an apprenticeship as a construction worker, went to the Foreign Legion, and was a seaman and a tramp. Now, he is working at the Warnow shipyard. Brigadier Bruno has a lot of sympathy and patience with the unconventional Josef, but Josef cannot fall in line with strict orders and again and again acts against the rules.

Susanne and Christian get to know each other during a wonderful week in summer - and fall in love. This, however, leads to conflicts: up to now, Susanne has been living with Wolfgang, a biologist. This shared life was harmonious and based on mutual trust. Wolfgang is not only resolute and in full command of social situations; he has also always been the stabilizing force in the relationship. This is precisely why Susanne now feels drawn to the unsettled, unsteady and frivolous Christian, the complete opposite of the calm, well-balanced Wolfgang. And Christian, working as a shift boss on a natural gas derrick, has become more aware of his personal and social responsibilities as a result of loving Susanne.
