Dragonfly Squadron is set in 1950 in the months before the beginning of the Korean War. John Hodiak stars as Major Mathew Brady, assigned to the base at Kongju to train South Korean troops for possible combat. These troops are to be used to protect civilians in the event of an evacuation, thus Brady is obliged to run them ragged in order to transform them into a lean, mean fighting machine. Despite the gravity of his job, Brady manages to find time to romance Donna Cottrell (Barbara Britton), the wife of an American doctor (Bruce Bennett). The Casablanca aspects of this triangle are the only forgettable aspects of this taut and timely adventure yarn.
