In a collage of historical reenactment and original interviews, this film looks at the assassination attempts made on Hitler towards the end of World War II.

After another failed attempt, Gersdorff and his co-conspirators contact other officers to assist them with the assassination of Hitler.

Gersdorff attempts to convince various high-ranking officials to join their plan, but not everyone believes that a coup would be the best solution for Germany.

Germany is under attack and time is of the essence, but it is difficult to find co-conspirators. When Claus Schenk Graf von Stauffenberg returns to Berlin, it seems possible that they have found a potential source of help.

What must come after the assassination? Stauffenberg and Gersdorff discuss their strategies and their doubts.

Claus Schenk Graf von Stauffenberg recruits Axel von dem Bussche, a young captain haunted by Nazi atrocities he has witnessed, as Hitler's so-called "European Fortress" begins to crumble.

Stauffenberg begins to consider whether to attempt the assassination of Hitler on his own.

More missed opportunities to stage an attempt on Hitler's life lead to confusion and suspicion.

Stauffenberg is only able to smuggle one of the bombs into the meeting and asks to be seated close to Hitler.

An explosion is set off, and Stauffenberg tries to leave as quickly as possible.
