Synopsis

Larry, apparently a wealthy young man-about-town, romances Vera, who has developed a new invention, a gas mask, for use in the war. Larry leaves Vera's house unaware that German spies are attempting to steal the plans for her invention. At a restaurant, Larry turns out not to be wealthy, but simply one of the waiters. When Vera and her father arrive at the restaurant, they are shocked to see Larry working there, but even more shocked when the restaurant owner turns out to be the ringleader of the gang of spies. The gang attempts to steal the plans, with only Larry to rescue both the papers and Vera.
