Right, everyone knows Tiva a going to Paris! But is it an undercover op of just a normal fact finding mission??

They have to escort an ambassador of something back to Paris, but apparently there is a threat of a hit on the plane back to Washington.

i think it's a bit of both because they get stuck in the same hotel room so obviously something interesting will happen but it'll become meer serious once they get on the plane back to washington and realise that there's danger in the plane.
