Will arrives at the BAU office with news that JJ has gone missing. On JJ's directive if she ever did go missing, Will has come to inform Mat, who would "know what to do" as the two are still working on a top secret case from their joint State Department days. This news surprises the rest of the team, as they had no idea JJ and Mat even knew each other prior to him being appointed Section Chief. However, they all discover that Mat is also missing, which they fear the worst for both JJ and Mat. Hotch is able to find out some basic information about what JJ and Mat were working on - that is was an Afghanistan based mission in trying to locate Osama bin Laden - but the BAU is told by the State Department not only to mind their own business as their disappearances are a State Department matter, but that they are to cease any work in trying to find either JJ or Mat or face the consequences if they do. The team ignores this directive, but they know that they have to work clandestinely to avoid detection by the State Department. They call in reinforcements in the form of Emily, who was in contact with JJ during her State Department years, and thus may have extra insight into what JJ was working on. They quickly discover that the person who has probably kidnapped JJ and Mat is a man named Tivon Askari, who worked as a translator on Mat and JJ's crew in Afghanistan but who was discovered to be a double agent, one who went to the highest bidder. But the team not only has to find out what Askari's goal is and where he may have taken the pair, but they also have to find out something that JJ already knows about someone else in their Afghanistan crew to uncover the full details and thus JJ and Mat's location.
