The Manager of the B & A (1916)

Dan Oakley becomes a railroad manager and his attempt to slash expenses by layoffs and lengthening hours incurs the workers' wrath. With the help of Griffith Ryder, labor leader and newspaper editor, they call a strike. The water main which supplies the railroad yards is cut, and a hot engine starts a fire. With water unavailable, the fire spreads to town, but through his superhuman efforts, Oakley gets it under control. His heroic moves win favor with the workers, and the strike is history.
