Set amid the conflict-torn regions of Ingushetia and Chechnya, the story is told through a tense interrogation. Sergeant First Class Jack Kellar, an undisciplined member of a CIA black ops unit, is pressed by an unknown interrogator to explain his recent actions against the Seventh Wave, an arms-smuggling terrorist organization blamed for a string of attacks. Kellar is warned that unless he cooperates, he will be disavowed, court-martialed, and imprisoned for life. Reluctantly, he begins to recount the events of the preceding days, in which his unit assaulted Seventh Wave strongholds and he uncovered a chilling truth: the group is led by William Lennox, a former CIA operative long presumed dead. As his account unfolds, the hunt for the Seventh Wave grows ever more personal and dangerous.
