The Romantic Age(1927)

Engaged to middle-aged Eugene O'Brien, Alberta Vaughn develops a yen for O'Brien's handsome younger brother Stanley Taylor. But when Taylor succumbs to her charms, she spurns him with a severe tongue-lashing. Understandably confused, the mild-mannered Taylor turns nasty, causing a rift between himself and O'Brien. The two brothers are reconciled when one saves the other from a burning building.
