The doltish but self-confident and self-congratulatory Private Snafu is in possession of a military secret during World War II. Over the course of the day, spouting rhymed couplets, he divulges the secret a little at a time to listening Axis spies. He tells his mom some of the secret when he calls her from a phone booth; the rest he spills to a dolly dolly spy who plies him with liquor. Snafu's loose lips put himself at risk.
