The Power Within (1921)

Millionaire shipbuilder Job Armstrong has built his company up from nothing, and believes that his own abilities are more than enough to make him even richer and more successful, despite being reminded of the biblical story of the man who shares his first name. It comes to pass that his son-in-law, Count Bazaine, is being paid by a foreign power to gain control of the shipyards, and stops at nothing, including murder, to do so. After a series of tragedies and deaths of his loved ones, caused by Bazaine, Armstrong is in the depths of despair when a higher power shows him a glimmer of hope among his misery.
