Although they never got off Warner Brothers back lot this 77 Sunset Strip story takes Efrem Zimbalist all the way to Switzerland where he gets a bit of romance in with hotel desk clerk Maria Machado. He's also met there by Kurt Kreuger who is an Interpol agent.
Both these guys are after a pair of international crooks played by Miguel Angel Landa and Albert Paulsen who stole some negotiable securities in Los Angeles while they were being transferred there under the not so watchful eye of Stu Bailey.
That blot on Bailey&Spencer's record cannot remain so Zimbalist has tracked the men to Switzerland. He and Kreuger want to bag the crooks and the loot at once.
However all is not as it appears with the characters, but PI Stu Bailey isn't fooled.
And Bailey&Spencer remove a blot from their record.
