After the Israelis accidentally bomb a school full of children, MI-5 receives information from the Venezuelan security service that the Americans will assassinate their President during an upcoming visit. The Americans are none too pleased that the British found a way to defuse the tense situation with Iran so Harry doesn't put the attempted assassination of a foreign leader on British soil past them. In return for helping them, the Venezuelans offer to tell the British the details of an upcoming retaliatory attack on British schoolchildren. Meanwhile, the agents learn that a disfigured and mutilated body of a young man - who had obviously been tortured - has been found. They believe it may be Zaf. Bob Hogan tells Adam it's the work of a group known bas the Redbacks, headed by an American ex-Marine. They've set their sights on kidnapping and extracting information from intelligence officers and their next target is a member of Section D.
