A farmer's horse attempts to enlist in the U.S. Army, but he is rejected when he flunks the physical, despite his strong attitude about it. Dejected, he finds himself in a phony battlefield, which teaches him what war is really like. He decides to knit sweaters as a way to help fighting soldiers overseas.
- This cartoon marked a new change in direction for Chuck Jones, where he eschewed the slow-paced, Disney-inspired style for which his earlier cartoons from the late-1930s and early-1940s have been known in favor of making fast-paced and more comedic cartoons like this one. It also marked the first time Chuck Jones directed a cartoon which uses World War II as its subject matter.
- This is the last cartoon to have WARNER BROS. and Present before they change to a new font.
