Uncle Sam's heavy target practice of a nearby fort jars little seven year old Marion's doll from the table in the nursery, shattering it on the floor. The Child is heartbroken at her dolly's fate and at a loss to understand the cause of it until the nurse, to pacify her, explains that the firing of Uncle Sam's guns at the fort jarred the dolly off the table. Upon learning this little Marion becomes indignant and decides to write a letter to Uncle Sam complaining about the damage. To humor her the nurse good naturedly aids her in carrying out her desire and the letter is mailed. At Washington. D.C., Marion's letter to Uncle Sam is opened in the postmaster general's office and turned over to the War Department where it receives immediate attention. Orders are issued to the commanding officer at the fort to investigate the damage and make such compensation and apologies as may be deemed proper. A committee of two young officers is appointed at the fort and they proceed with due ceremony to investigate the damage claim. At Marion's home they are surprised to find the claimant to be a pretty little child. They consider the matter gravely and while there are presented to Marion's sisters, two most attractive young women. The young officers lose their hearts to the girls and report progress to their commanding officer. Secretly they each buy a huge doll and repair to Marion's home to present it to her. Again they meet the young ladies who receive them most graciously. Little Marion is quite happy with her two unexpected new dollies, while her older sisters seem equally happy with their unexpected sweethearts; the result of a jar.
