Four Vietnam veterans are forced to confront a shared, traumatic past when a series of brutal murders begins to mirror a secret from their time in the war. The protagonists—a doctor, a lawyer, a laborer, and a writer—must navigate their disparate lives and personal demons to track down an elusive killer who is systematically targeting people from their history. Their investigation spans continents, moving from the political corridors of Washington, D.C., to the chaotic urban environments of New York and the haunting landscapes of Southeast Asia. The narrative employs a shifting, multi-perspective framework that emphasizes the psychological erosion caused by long-buried secrets and the persistent shadow of wartime atrocities.
