The boys are back in town — and Paris is burning!

For Special Agents of the Department of Diplomatic Security, Taylor MacAllister and Will Brandt, the strain of a long distance relationship is beginning to tell after eleven months of separation. A romantic holiday could be just the thing to bridge the ever-growing distance, but when Taylor spots a terrorist from the 70s, long believed dead but very much alive, it's c'est la vie.

Now instead of sipping wine and seeing the sights, the boys are chasing a wily and deadly foe through the graveyards and catacombs of Paris.

Of course, it could always be worse — and soon it is.
