Mrs. White is compelled to discharge her nurse on account of carelessness. The following day her friend calls to take her to a matinee. But she cannot go, as there is nobody to mind baby, so they decide to leave it at Mr. White’s office in his care. Arriving at the office, they find Mr. White has gone out on business. They leave baby in the clerks’ charge, who do all sorts of things to keep baby quiet. They play hide and seek with it, next they play policeman. Jimmie is the policeman, and the wardrobe is the jail. Jimmie locks baby in for not having a license on her teddy bear and pockets the key. Now, Jimmie is sent out on an errand by another clerk, and forgetting all about baby, rushes out of the office. In the meantime Mr. White returns to the office, and finding it near closing time, orders his clerks to go home. They set the time lock on the safe and lock it. The scene now reverts to Jimmie, who is home eating his supper. Suddenly he remembers that he locked baby in the wardrobe. He arrives at the office just in time to prevent the men from dynamiting the safe, who are under the impression that baby is in it, after hunting all over for it. Baby is restored to the arms of its parents, and Jimmie gets his.
