Major Hugh North proving that a monumental binge and a wholehearted renunciation of his country can carry one far along the Party Line and be instrumental in acquiring vital information from far behind the iron curtain. North follows the line to a deserter and traitor, gets the key to a hidden microfilm, and with Jingles Lawson (newspaperwoman who gets a chance at being Mrs. North) makes a dangerous, mad dash to safety in Turkey. Durable characters who trigger think and act, this is adapted to current events interest.
