A famed American surgeon is decoyed to a middle European country to perform a life-saving operation on its dictator. When the leader dies anyway, he is replaced by a look-alike and the doctor is pursued by the secret police so that he can never reveal his knowledge of the dictator's death. He seeks help from an English-speaking actress and both of them are then forced to flee.
