Das Mädchen aus der Ackerstraße. 1. Teil (1920)

The underage daughter of a degenerate couple living on Berlin’s Ackerstraße flees her parents’ apartment because she is subjected to ongoing abuse. After collapsing on the street, she is taken in by a young university professor, who cares for her for an extended period until one day her benefactor—with whom the girl from Ackerstraße has fallen in love—begins an illicit relationship with her.
