When a failed op results with a top asset being murdered and vital intel stolen, two CIA operatives race to apprehend a cyberthief who may have inadvertently discovered clues related to an impending attack against America.

What Valentin said about the CIA not legally being authorized to operate in the United States. That's the home turf of the FBI and you can be sure the FBI vigorously defends their home turf against encroachment by other agencies.

Why did you named your script "The Demeter Code"?
Is it in reference to the Ancient Greek Goddess of Harvest?
Why two CIA operatives and not just one?
BTW, CIA operatives are not legally authorised to operate on U.S. Soil, the operatives should be military, Homeland, NSA, FBI or any other Federal organisations.
The current logline remind me of "Die Hard 4.0".

"After their system is hacked, a hard nosed CIA officer is forced to team with a nerdy computer consultant to catch a cyber thief who inadvertently stole vital information about an impending nuclear attack."
