On the night before Christmas, Detective Alex Cross is at home celebrating with his family. But when Alex’s phone rings, he knows that this won’t be a merry Christmas.

A father has taken his children and ex-wife hostage. Armed to the teeth and high on crystal meth, Henry Fowler is dangerously unstable. The lives of everyone in that house are hanging by a thread.

As this suburban nightmare is unfolding, another far greater threat is approaching. It will be a terrorist attack like Washington DC has never seen, and when nobody expects it.
