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

They have to escort an ambassador または 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 もっと見る serious once they get on the plane back to washington and realise that there's danger in the plane.
