Main Street Today

set in World War II has a factory owner who produces the breech block for a key piece of army artillery. The military wants to increase production by 50% but they can barely meet their production targets as it is. Going to a third shift in the plant will need manpower, 500 in total, that is sorely missing due to the number of men in the military. The film then looks at the town's main street seeing where the workforce might come from. (imdb)
