A Modern Hero (1934)

Pierre is a handsome young circus rider whose mother has long tolerated his amorous adventures but becomes genuinely concerned when he actually falls in love. She reveals to him that he's the son of a wealthy man, whom she could not marry because of the circus life. But Pierre uses this knowledge as a springboard to wealth and fame himself, as an automobile-maker in the early days of the industry, and as a munitions dealer when war breaks out. But his ambition seems to take its toll on all his relationships, and he seems unaware that he is over-reaching himself.
