The Dwelling Place of Light (1920)

When stenographer Janet Butler's malevolent employer, Claude Ditmar, starts to sexually harass her after carrying on an affair with her younger sister Elsie, Janet decides to quit her job and join forces with the disgruntled mill workers. While attempting to avert a looming strike, Brooks Insall, one of the mill's major stockholders, meets Janet and the two fall in love. In the ensuing chaos of the strike, Ditmar is shot by Janet's deranged mother, and Janet is imprisoned for the crime. Insall exonerates her, replaces Ditmar as the mill's manager and rescues Elsie, whose shame had forced her into exile. Elsie's return restores Janet's mother's sanity, and they all face a happy future together.
