Flying the Jaguar bomber in a Cold War West Germany, Nick Gleason is, perhaps, at the peak of his career but he is a loner struggling with his conscience and he begins to question the morality of his role. If war in Europe breaks out, he would be tasked to deliver a thermo-nuclear weapon to a target in the East. Two British fighter aircraft, one a Phantom, the second a Jaguar piloted by Gleason, converge at low level over the Osnabruck Ridge on the North German Plain. One is armed with a practice nuclear bomb, the other simply conducting 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 encounter that threatens to jeopardise their very existence. Was a mid-air collision inevitable from the outset or could the, seemingly, inexorable chain of events have been broken? Was destruction predestined? The countdown to impact is underway.
