At the peak of his career, Nick Gleason is a loner struggling with his conscience. Flying the Jaguar bomber in a Cold War West Germany he begins to question the morality of his nuclear role. Two British fighter aircraft, a Phantom and the Jaguar piloted by Gleason, converge at low level over the Osnabruck Ridge on the North German Plain in West Germany during the Cold War. One is armed with a practice thermonuclear bomb, the other simply intercepting a formation of German fighter bombers on a routine training exercise but their flight paths are destined to cross. Events have been far from routine as the crews are drawn towards the confrontation that threatens to jeopardise their very existence. It seems that a collision was inevitable from the outset but could the, seemingly, inexorable chain of events have been broken or was destruction predestined? The countdown to impact is underway.
