June 1944: the SAS parachute deep into occupied France, to wreak havoc and bloody mayhem. In a country crawling with the enemy, their mission is to prevent Hitler from rushing his Panzer divisions to the D-Day beaches and driving the Allies back into the sea. Led by Captain Patrick Garstin MC, a man supposedly invalided out of the military due to his war injuries, rarely had a wilder bunch of raiders been assembled. Having blown to pieces scores of prize targets, Garstin's patrol executed one of the most daring escapes of the war ... only to fall victim to shocking betrayal. Captured, imprisoned and tortured terribly by the Gestapo, they faced execution in a dark French woodland on the orders of Hitler himself. But miraculously, two would escape, triggering one of the most-extraordinary Nazi-hunting operations ever. Summer 1945: with WWII officially over one team embarked upon a shadow war all of their own. Armed with knowledge earned first-hand in the torture chambers of the Gestapo, the race was on to bring to justice the Nazi war criminals who had murdered their brothers in arms. In a deniable, deep-cover operation backed by Winston Churchill himself, the 'the Secret Hunters' would expose Nazi Germany's darkest crimes, doggedly tracking down those they most sought.
