A disgraced CIA operative faces interrogation in a shadowy facility as an unseen questioner demands answers about his brutal campaign against the Seventh Wave, a ruthless terrorist faction terrorizing the Caucasus region. Sergeant Jack Kellar, a reckless member of a covert black ops unit, finds himself cornered—cooperate or face lifelong imprisonment and complete abandonment by his agency. Through his reluctant testimony, a horrifying revelation emerges: the terrorist organization is commanded by William Lennox, a ghost from Kellar's past and a former intelligence officer thought long dead. As Kellar pieces together the events leading to this interrogation, the line between hunter and hunted blurs, transforming what began as a straightforward counterterrorism operation into a deeply personal and increasingly perilous reckoning.
