The Strongest (1920)

Harle, a successful French businessman, is so absorbed with his factory that he neglects his wife Claire. One day, Harle's old friend Henri, the Marquis de Puymaufray, comes to visit, and Claire falls in love with the cultured and sensitive man. Several months after his departure, Claire gives birth to a baby girl, Claudia, and dies shortly afterward from neglect and depression. Twenty years pass and Claudia has grown into a beautiful woman. Her father wishes her to wed a count, but she loves Maurice, a young American. During a labor dispute, Claudia is abducted by her father's disgruntled employees and held for ransom. The marquis, who has long watched over the girl, loses his life in a rescue attempt, but Maurice finally succeeds in liberating his sweetheart. After the marquis' death, it is revealed that Claudia actually was his daughter, and Harle, crushed, retires to his country estate, freeing the girl to voyage to America with the man she loves.
