The Our Gang kids join in America's national defense program in this subject. Thinking that the town needs to be defended the kids organize an army but then are told that they can best be of help by collecting material that can be used in the defense program. The gang sets to work gathering old inner tubes, tin foil, pots and pans. A parade is held. Our Gang passes in review laden with their spoils followed by the "Infantry Reserves," a group of babies of toddling age with diapers for uniforms.
