Tom (Billy Halop), Pig (Huntz Hall), String (Gabriel Dell), Ape (Bernard Punsly) and Rap (Bobby Jordan), collectively known as "The Dead End Kids", are learning to become aeronautical mechanics in the National Youth Administration Work Program plant. The Kids really want to fly and think they have learned enough to become pilots.
Their dreams of flight will not come true because the Civil Aeronautics Authority flight school requires them to have completed high school, something none of them have achieved. Seeking out a flight school, the Kids go to work for unscrupulous crop dusting operator Arnold Carter (Victor Jory). Quickly realizing that pilot training is unlikely, Carter's manager, Mr. York (Wallace Ford) puts them to work as mechanics.
