State Secret (1950)

While working in England, an American surgeon Dr. John Marlowe is invited to Vosnia (a fictitious East-European country) to receive an award and demonstrate his life-saving surgery. Unwittingly caught in the middle of a dangerous and corrupt series of political events, Marlowe then becomes the object of a shoot-to-kill, vicious pursuit. Fleeing, he seeks help from an English-speaking actress, Lisa Robinson, and the two attempt to escape across the treacherous mountains of Vosnia.
