Stalemate NSA

A technically savvy terrorist cell has devised a way to keep NSA from
listening to their planning for simultaneous attacks on multiple U.S.
targets.

By the time a crack team of experts finds a way for NSA to eavesdrop on the
terrorists, it is too late. The terrorists are already conducting dress
rehearsals of their planned attacks. But the actual targets and the attack
date are still shrouded in secrecy.

As the targets and the attack date become known, the terrorists take an
unexpected change of direction and unveil a plan that throws the President,
his cabinet, and his senior advisors into panic. The final outcome is
impossible to predict.
