Desc: On the Jump: Directed by Raoul Walsh. With George Walsh, Frances Burnham, James A. Marcus, Henry Clive. During World War I, an enterprising and patriotic reporter named Jack Bartlett interviews President Woodrow Wilson on the importance of the Fourth Liberty Loan. Jack returns from Washington to find that Otto Crumley, a German sympathizer, has taken control of his newspaper, and when Crumley tears up the story, Jack resigns and joins the Liberty Loan campaign. After raising a large sum of money for the government, Jack succeeds in preventing a strike in a local munitions plant. Later, he learns that Crumley, actually a German agent, has stolen a secret gasoline substitute formula invented by William Desmond, the father of his girlfriend Margaret. Crumley imprisons Margaret, but Jack rescues her and then swims out to the schooner on which Crumley is making his escape. The spy apprehended, Jack turns the ship's guns on a German submarine and sinks it.
