During a routine inspection of surveillance equipment at the Turkish Embassy, Zoe and everyone inside are suddenly taken hostage by terrorists demanding the release of their imprisoned parents. If Zoe's cover as a PR consultant is exposed, her life will be in grave danger. The situation escalates when Harry discovers that this embassy attack is merely a diversion for a far more significant plot unfolding behind the scenes.
