"Major March, U.S. Army Reserve, is sent undercover to Moscow, where a captured American U-2 pilot is on trial. As usual, Milo has no plan but makes it up as he goes along. He will have mere moments to retrieve a coded message and snatch the pilot from the Communists’ hands—but things don’t go exactly as expected."
