What happens
Secret agent Mr. X, played by Herbert Marshall, works to stop a leak of Soviet military plans concerning Iran. A courier named Thurston, carrying microfilm, boards a plane from Tehran to Baghdad, where he meets passengers including an English archaeologist, James Gilbert, and his nurse, Lisa Hussein. The plane is downed and the mystery deepens as the group is pursued by agents and the stakes around the hidden information rise. The Man Called X aired on February 24, 1951, on NBC as a Saturday night feature.

Written from the episode itself; it never gives away the ending. Every recording is remastered for the stream: cleaned of rumble, hiss and mains hum (and the old TV whine where we found it), then levelled in two passes to steady broadcast loudness, so one show is never quieter than the next.
