Masquerade

Charlie and Maureen accompany President Payton to Qatar on a diplomatic trip. What begins as a standard mission of diplomacy becomes a disaster when a Qatar national infiltrates the American embassy claiming to be CIA. Constance tasks Charlie to find out if he's telling the truth. Meanwhile Lucas, Dash and Kurt work to track down Al Moosari, believed to be a direct link to Omar Fatah. Kurt has a run-in with a walk-in who claims to have found a valuable 'backdoor' into highly valuable communications. Nick, still MIA, is violently interrogated by a masked man. Charlie finally takes desperate and dangerous measures to remember the events of the convoy attack.
