An American Air Force colonel (Wayne) in charge of an Alaskan Air Force base falls in love with a defecting Russian jet pilot (Leigh). They marry, but Wayne suspects Leigh is a spy planted to find out top U.S. secrets. He pretends to defect with her back to Russia to see what he can find out, but they again flee. Ludicrous plot is saved only by spectacular flying scenes, some performed by Chuck Yeager. Although this was filmed in 1950, it took seven more years to be released because producer Hughes couldn't keep his hands off it.
