The year is 1943 and Coronel Claus Schenk von Stauffenberg has just been transferred to Berlin to serve under General Friedrich Olbricht, member of a resistance committee that begins to lay out a plan to assassinate Hitler. Olbricht already has more than 200 recruits in different levels of German society, including in the intelligence and counterintelligence divisions of the military. The objective is to eliminate Hitler, Göring, and Himmler, neutralize the SS, and install a provision government that would try to make peace with the West and stop the war. Von Stauffenberg, despite his war injuries (he has lost an eye and several fingers on one hand), wants to carry out the assassination. The conspirators have their doubt: Is he capable of activating the bomb? They finally concede to letting him do it because they understand that his handicaps will reduce outside suspicions. After July 1st, von Stauffenberg makes several attempts at completing his mission, but is never able to catch the targeted victims together at the same time. Finally, though, on July 20, 1944, the perfect opportunity presents itself. .

Chinese Summary/中文概要： 1944年7月20日，一批對納粹深惡痛絕的德國軍人密謀策劃了一起暗殺納粹狂魔希特勒的行動，一枚炸彈在希特勒的“狼窩司令部”發生爆炸，但炸彈只炸死另外4人，希特勒卻死裡逃生。歷史學家一直認為，倘若事成，二次大戰可能提早結束，幾百萬條性命不致白白犧牲，歷史也將重新改寫。
