Harry Kellem (Russ Conway), an American businessman working in Tokyo, has been accused of murdering his Japanese wife. The actual culprit is Kellem's brother-in-law Toshio Masaki (Khigh Dheigh), who for political reasons is bent on destroying Japanese-American diplomatic relations. Assigned to clear Kellem and expose Masaki, the IMF embarks upon a series of clever ruses, wherein Paris impersonates a Kabuki dancer, Willy poses as a martial arts champion and Dana disguises herself as the late Mrs. Kellem. Originally seen on October 31, 1970, "The Butterfly" was scripted by Eric Bercovicci and Jerry Ludwig, from a story by Sheldon Stark.
