After her father suffers financial ruin, Norma Webb advertises for boarders and finally accepts the application of young philanthropist Hugh Godwin. Norma is deeply in love with Hugh, but she mysteriously refuses his proposal of marriage. Later he learns that some time ago she had married the scoundrel who swindled her father. One night the husband enters her room and tries to force his attentions on her, whereupon she shoots him and flees. A detective discovers the body and threatens to expose Norma unless she uses her influence to secure for him Hugh's financial secrets. Desperate, Norma marries Hugh and obeys the blackmailer's orders until finally, unable to endure her own dishonesty any longer, she confesses everything to her new husband. Hugh and Norma track the detective to his home just in time to witness him murder the first husband, who merely had been wounded by Norma's shot. The detective is arrested, leaving Hugh and Norma free to enjoy their happiness.
