When Richard Cameron, a secret service agent tracking down international spies, is kidnapped by the enemy, Mirian Somerset, to whom Richard has been surreptitiously married, believes that he is dead. Mirian then acquiesces to her mother's wishes and marries the rich and dissipated Charles Van Horn in order to recoup her family's fortune. When Richard suddenly returns, Van Horn finds Mirian with him and, enraged, attacks him. In the struggle that follows, Mirian strikes Van Horn, accidentally killing him. Richard, who must return to his mission overseas, is forced to leave Mirian alone. When her brother Page is arrested for Van Horn's murder on circumstantial evidence, Mirian is torn between fear of revealing her own crime and horror at her brother's conviction. Just before the boy is sent to the electric chair, however, Richard appears with the governor's pardon and Page is freed, restoring peace to Mirian's turbulent life.
