When pilot Dick Bennett (Dick Merrill) undertakes a flight in stormy conditions to save a dying girl, he brings the aircraft in, despite warnings that it is too dangerous. Later, he meets socialite Gail Strong (Paula Stone), who is interested in aviation and persuades Bennett’s aircraft engineer friend Bill Edwards (Weldon Heyburn) to try a parachute jump. Her fiancé, Baron Hayygard (Ivan Lebedeff) pledges that he will win the National Air Races, to make her keep her promise to marry him, and resorts to desperate measures, knocking out Bennett. When Bennett is unable to fly his untested racer, Edwards takes it up instead, but crashes. Strong realizes she is in love with Edwards, but he is critically injured. A doctor in England has life-saving serum that Bennett and Jack Carter (Jack Lambie) are determined to bring back to save their friend, by making a record-breaking round-trip to London. Coming back through a raging storm over the Atlantic, their aircraft is struck by lightning, disabling their radio. When contact is lost, Coast Guard ships are deployed, but the intrepid flyers make it in.
