Upon reaching retirement age, Colonel Cornelius Stockton (Harry Carey (actor)) is forced to leave the US military, accepting a job running the Trans-World Air Lines School of Aeronautics in Glendale, California. "Stag" Cahill (Richard Dix), an old friend from the war, is the pilot on the commercial airliner taking him to Glendale. The colonel asks him to join the school staff, but Stag would rather fly. When the colonel arranges for Stag, a reservist, to be recalled to active duty, he orders him to take the assignment as his assistant. Stag reluctantly complies.
