Plot
During World War II, members of The Dead End Kids, a youth gang, Billy “Ace” Holden (Billy Halop), “Bolts” Larson (Huntz Hall), “Stick” Munsey (Gabriel Dell), Ace’s brother, Eddie (Gene Reynolds) and “Greaseball” Plunkett (Bernard Punsly) are working in an salvage yard owned by Ace’s father (Eddy Waller), recovering aircraft parts. While making their escape from robbing a bank, members of a fifth column organization, the “Order of the Black Dragonfly”, steal the boys’ wrecking truck.

When agent Don Ames (Richard Lane) from the State Bureau of Investigation, returns their truck, the gang who is distrustful of authority, especially, the “cops”, refuse to give a description of the men who stole the truck. Don asks Jerry Markham (Frank Albertson), leader of the (the Little Tough Guys), called the “Junior G-Men” to ask Ace for help. Both boys are passionate about aircraft and flying and agree to join forces.

Meanwhile, Axis agents working for “The Baron” (Lionel Atwill), a Japanese leader of the “Order of the Black Dragonfly”, have more plans for the junkyard, especially the aircraft parts stored there. The Baron has orders to destroy anything that may help the Allied cause. Ace and Jerry join together to go look for the enemy saboteurs, and find their secret hideout in a farm outside the city.

The enemy agents capture Ace and Eddie, who escape in one of the aircraft that the Baron uses. Their takeoff ends in disaster as Ace hits a fence, tearing off the landing gear and punching a hole in the gasoline tank. The boys parachute to safety and make their way to government headquarters.

The Dead End Kids and Junior G-Men lead the government to the Baron’s base and a furious battle takes place. Ace and Jerry personally capture the Baron and receive the government’s thanks for bringing the enemy agents to justice.
