In order to secure a change of scene after a nervous breakdown, Louise Gray goes to Silver City, and obtains employment in the office of the Good Hope Mining Company, where Tom Price is cashier. Tom and Louise fall in love. Louise’s happiness is clouded by worry over her mother and sister, who are very poor and in ill health. A large sum of money for the payroll is received and placed in the safe, the combination of which is known by both Tom and Louise. Carlton, the manager, is called away from the town, and during his absence word is received of some trouble at the mines. Tom starts for the mines, saying he will return the following day. After Tom’s departure, Louise hears of a gang of outlaws operating in the region, and becomes much concerned for the safety of the money. In her nervous state this effects her so strongly that, in her sleep, she goes to the office, removes the money from the safe, and conceals it. Tom, hearing of the outlaw gang, has returned and sees her take the money. He thinks that she has been unable to resist temptation and has stolen the payroll. Being unable to secure the money and restore it to the safe, Tom, determined to protect the girl, declares himself to be the thief when the loss is discovered. Both Tom and the girl are heartbroken, each thinking the other a thief. The outlaws attempt to raid the town, and in a fight with the sheriff and citizens, are killed or captured. The elimination of danger from the outlaws acts upon Louise’s subconsciousness, as did the original fear of them, and that night she again walks in her sleep, restoring the money to the safe. This time she is seen by the sheriff, Tom’s friend. The sheriff explains to Tom and Carlton the facts, but, to save her feelings, they are kept secret from Louise, she being told that it was all a mistake, that the money was at all times in the safe. Louise gets well and all probability of a recurrence of somnambulism is removed by the elimination of worry over her mother and sister. When she returns from her honeymoon she finds that Tom has brought them West to live with them.
