It's early in the Cold War, and no job is more important than Air Force test pilot. Maj. Lincoln Bond (William Holden) is an ace flier, but because he was a captive during the Korean War, Brig. Gen. Bill Banner (Lloyd Nolan) thinks the emotionally wounded Bond isn't ready for the job. Making matters worse for Bond, his ex-girlfriend, Connie (Virginia Leith), is spending her free time with Banner. But, in a series of dramatic events, Bond impresses fellow pilots and earthbound observers.
