The Truth About Helen (1915)

Helen Moore (Grace Williams) runs off with the nephew of Senator Foote, but when their car breaks down, they go to a hotel. A conference is going on there, and the boss politico is choosing his candidate for district attorney. Hugh Graham is the boss's favorite, and also Helen's ex-fiancee. The nephew tries to force himself on her and Graham hears her cries for help. When he rescues her, he is seen by his rival, Gregory, who assumes they are having an affair. He threatens to expose this, and to protect Helen, Graham withdraws from the nomination.
