In Yugoslavia, Solo and Illya are aided by Marion Raven (Jill Ireland) in stopping Gervaise Ravel (Anne Francis) and her partners from using a fear gas to overthrow various governments. While two of them are captured, two of them escape, and the story continues in "The Giuoco Piano Affair"

Solo and Illya protect Miranda Bryant, the wife of a presidential candidate, from a THRUSH plot to kidnap her, not realizing that she has already been kidnapped and replaced with a double Irina, an unwitting dupe of THRUSH. When they do catch on, the candidate, Senator Bryant and his aide Fairbanks, agree to play along but Fairbanks is the one behind the plot to put a THRUSH agent in the White House.
