To prevent Ben Farraday from exposing the whereabouts of her brother, an escapee from prison, Nan Kennedy agrees to steal important papers from Farraday's enemy, John Lawson. Nan is caught and Lawson agrees to let her go free on the condition that she do his bidding for a year. After arranging a wedding between Nan and Billy Bond, the son of a man whom he blames for stealing his wife, Lawson shocks everyone during the wedding reception by announcing that Nan is a thief. Billy runs away and turns to drink and Nan's only thought is to seek vengeance against Lawson. Knowing that his one weakness is his belief in spiritualism, Nan poses as a medium and advises him to sell certain stocks. The next day, Lawson finds himself ruined. Meanwhile, Billy vows to kill Lawson, leaving a note to inform his father of the deed. Discovering the note, the elder Bond rushes to Lawson's house and announces that Billy is actually Lawson's son. Overcome, Billy's nerves break and he cries for Nan. Lawson, repentant, finds her and a happy reunion takes place.
