Schwalk, the new shaft foreman of a road construction brigade, is a go-getter and used to success - both at work and with women. But this time things don't go so smoothly. Although he initially has an easy time with the brigadier Erika, who falls in love with him, things come to a head at work. His ambition to win a competition causes him to slip up during road construction. Erika is outraged by his selfish behavior and suspects that he is just looking for an erotic adventure with her. She turns her back on him. However, Schalk recognizes his mistakes and does everything he can to make up for the damage - to the building site and to Erika. The road is handed over on schedule.
