The Burden of Proof (1918)

Elaine Brooks marries Robert Ames, a member of the United States Department of Justice. The Germans, who are anxious to secure some papers that Robert possesses, employ Viola Durand to get to Robert through Elaine. Viola tricks Elaine into giving her the papers and also procures a letter that seems to establish Elaine as the traitor. George Blair, an official at the Department of Justice, finally tricks Viola into confessing her guilt, thus clearing Elaine's name.
