An anthropologist investigates the origins of human evolution. She had suffered a mental trauma during her childhood when her father, a submarine captain, died during the war. This trauma periodically destabilizes her condition. The ghosts of a prehistoric past and a violent death collide in the subconsciousness of the scientist to give birth to an unexpected theory of the origins of human beings.

Mixture of documentary and fiction about the dictatorial 1930s, loosely based on the utopian fantasies of Fritz Lang and about the forbidden passionate love affair between a photographer and his model.
