Spies is part of the Private Snafu series of animated shorts produced by Warner Bros. during World War II.

Private Snafu has learned a secret, but the enemy is listening and he'd better zipper his lip, and keep his brain secure with a padlock and chain.

However, Snafu little by little lets his secret slip (by telling the audience, calling his mom, telling a magazine salesman, and drunkenly relaying it to a bar girl who works as a Nazi German spy, due to drinking an entire bottle instead of the glass he was given): his ship is about to set sail for Africa at 4:30.

The information is picked up by spies and quickly relayed to Führer Adolf Hitler, who orders the Nazis to attack the American fleet, which they do, shooting Snafu with torpedoes when he falls in the water after yelling for the ship to go "full speed ahead" to escape.

A scene in which Private Snafu becomes drunk is musically accompanied by an excerpt from Raymond Scott's composition, "Powerhouse".
