This wacky escapade takes Abbott and Costello on a high-flying adventure as new recruits in the Army Air Corps. When their friend Jinx Roberts (Dick Foran), a hot-shot carnival flyer, joins the army, the duo decide to enlist too. The three form a "women-haters union" until Jinx meets up with a beautiful USO singer (Carol Bruce) also stationed at the air corps base. Jinx has problems fitting into the corps while Bud and Lou get involved in a hilarious love triangle that turns square. They go for the ride of their lives in a plane they didn't think could fly.
