A foreign spy named Baron von Huldorf, an agent who works out in the open, is arriving in the States from his home country to work in the Bataria embassy. Bart Regan and Sally Norris are to pretend to be traitors selling secrets to him, actually "harmless information such as he'd undoubtedly dig up anyway" while at the same time preventing him from learning anything useful. Their success sends the Baron home in frustration but irks the heck out of another agent named Lorenzo Rica who decides the pair have interfered too many times.
