Foreign Intrigue was one of the first major Hollywood films to be based on a popular TV series.
Plot
Millionaire Victor Danemore, living on the French Riviera, dies suddenly of a heart attack. His secretary, Dave Bishop (Robert Mitchum), wants to know more about his employer's life. Surprisingly, not even his young wife knows anything about her husband's background or how he earned his fortune. Bishop enters into a world of espionage and blackmail while uncovering Danemore's secret past. Clues lead Bishop to Vienna and Stockholm, where he learns that Danemore was blackmailing people who cooperated with the Nazis during World War II.
