Now that Calder Michaels is the new head of the DPD, changes are underfoot. Annie and Auggie, still reeling from the fiasco with the Chens, are pulled into their new boss's office and given their marching orders: Annie is to go to Vienna and make contact with international arms dealer Dion Stavros, and Auggie is to have no contact with her. He's been removed as Annie's handler, replaced by Calder himself. The news doesn't please Auggie a bit, not only because he doesn't relish the thought of being cut off from his girlfriend, but because it looks like Calder is Henry Wilcox's latest puppet and CIA mole.
But for now Annie and Auggie have to keep up appearances with their new boss, so Annie travels to Vienna with a new cover in place; now that her Smithsonian days are behind her, she'll be posing as a less-than-aboveboard importer/exporter, and trying to score work from Stavros. She smooth-talks her way into a meeting with the arms dealer, who offers her a job: find a buyer for his 25 missile launchers. But when the operative Calder sends to pose as the buyer proves too green, Annie finds herself on the wrong end of a gun. Good thing Auggie wasn't quite ready to give up his job as handler, and has secretly sent in a buyer of his own to save the day: Teo Braga. Although Teo's presence saves Annie's cover, the loose cannon has an agenda of his own that could make Annie's life a lot more complicated.
Meanwhile, Joan and Arthur - now back together - are trying to get a step ahead of Henry, and decide that it's time to bring in reinforcements of their own.
