The Dove on the Roof.

Three people from very different walks of life meet at a large construction site. Young, unmarried, self-confident construction manager Linda Hinrichs dedicates herself completely to her work and enjoys living more independently then most women. Daniel, a student works on the construction site to make money during his summer holiday, and impresses Linda with his spontaneous energy and idealism. Brigadier Böwe, an older, divorced man works his way from one construction site to the other and has lost his own personal happiness on the path to developing what was seen as officially suitable social standards. Both men try to win Linda over, not realizing that they are taking her freedom away from her.
