In the skies over Nazi Germany, RAF gunner Harry Wakefield faces a horrifying choice - jump from his crippled bomber without a parachute or burn to death as it crashes to earth. Harry jumps … and survives with barely a scratch. Twenty years later, a powerful earthquake rocks Harry's remote farm. Convinced that a plane has crashed on a nearby peak, he races up the mountain, only to discover the wreckage is unlike any aircraft Harry has ever seen. And something inside has survived. As dark agents of powerful organisations seal off the mountain, Harry must choose between his civic duty or revealing to the world the truth of a bizarre and fascinating phenomenon… One that Harry has witnessed before in the skies over war torn Europe.
