Plot

Documentary short film demonstrating the process by which waste fats from the kitchens of American homes can be transformed into the raw materials for explosives for the war effort.

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.—scgary66
