In this WW II musical, a young man suddenly finds himself in charge of his family when his father is called to war. To help the flagging spirits of local factory workers, the plucky lad, his siblings and his schoolmates put on a lively little show. With a little work, he even convinces Count Basie to come with his band.

Circumstances arise that result in a man impersonating his uncle. As the "uncle", he finds himself pursued by his girlfriend's aunt, who does not approve of their relationship.
