 Otis Bird s factory manufactures a part for howitzers that has been vital to the success of the war effort. Production must be stepped up. However, he has a problem getting enough workers to fill three shifts a day, because all the eligible men are either in the military or working at jobs declared essential. At a town meeting, the residents complain that it is impossible to hire workers for their own businesses as it is. The townspeople finally agree that Mr. Bird can hire women to work at plant, so that the people of "Main Street USA" can contribute to the final push that will lead to total victory.
