Mitch Rapp and his girlfriend Katrina Harper are on vacation in Ibiza, Spain. Moments after Katrina accepts Mitch's proposal of marriage, a jihadist cell lands on the beach and begins to attack the civilians with assault rifles. Amid the carnage, Rapp frantically attempts to find Katrina, but his fiancee is killed by the terrorists. Eighteen months later, Rapp, now consumed by his desire for vengeance, frequents an internet message board where the terrorist responsible for his girlfriend's murder quizzes Rapp on aspects of Islam and jihad. Having secured an invitation to meet him face to face in Libya, Rapp prepares to take his vengeance on the man responsible for his girlfriend's death, but before he can kill the terrorist, the cell is suddenly ambushed by U.S. Special Forces. Upset over the perception that he has been denied his vengeance, Rapp repeatedly stabs the terrorist he was after, who is already dead from the ambush, before being dragged out by the U.S. forces..
