Now that Falklands hero Major Patrick Gillard has been forced to resign from D-12, the supersecret section of British Intelligence, and his novelist wife has finished her manuscript, they're planning a third honeymoon … when Patrick's brother Larry, a schoolmaster overseeing an Outward Bound-like program, asks for help: someone has been sabotaging his outings. The Gillards tackle the survival course with disastrous results: Larry is wounded and hospitalized, while husband and wife are captured by a former nemesis, Lyndberne, now operating a school for terrorists and eager to use Patrick and Ingrid for torture/interrogation practice.
