Rough and tough Geoff Carter (Cary Grant) runs a tiny airline that cannot afford to miss any flights, despite the dangers along many of the routes. When Bonnie Lee (Jean Arthur), a performer who is falling for him, sees that Geoff is preparing to fly in violent weather conditions, she takes measures to make him stay. She's successful in her attempt, and two of his employees are forced to make the flight for him -- but Bonnie may have been correct about the potential peril of that flight.
