An extraordinary “snatch-and-grab” raid on Germany's secret radar installation, it offered Churchill's elite airborne force, the Special Air Service, a rare opportunity to redeem themselves after a previous failed mission - and to shift the tides of war forever.

Led by the legendary Major John Frost, these brave paratroopers would risk all in a daring airborne assault. With the help of a volunteer radar technician who knew how to dismantle the dish, as well as the courageous men and women of the French Resistance, they succeeded against all odds in their act of brazen robbery.
