Minnie is about to pour her bacon grease over Pluto’s dinner bowl as a treat, but a radio announcement reminds them that the glycerine which can be extracted from cooking fats is important to production of war munitions. Pluto decides that he would rather his treat be used to help Mickey and the other troops at the front, and he helps to collect grease to deliver to the local collection station – getting a better treat as compensation after all. The only film in which Mickey Mouse is shown in uniform, he is seen in a photo on the wall as a soldier.
