In a country in the grips of evil, in a police state where every move is being watched, in a world where justice and honor have been subverted, a group of men hidden inside the highest reaches of power decide to take action. Based on the true story of Colonel Claus von Stauffenberg and the daring and ingenious plot to eliminate one of the most evil tyrants the world has ever known.

A proud military man, Colonel Claus von Stauffenberg is a loyal officer who serves his country all the while hoping that someone will find a way to stop Hitler before Europe and Germany are destroyed. Realizing that time is running out, he decides that he must take action himself and joins the German resistance. Armed with a cunning strategy to use Hitler’s own emergency plan – known as Operation Valkyrie – these men plot to assassinate the dictator and overthrow his Nazi government from the inside.
