Two lone assassins, Elser and Bavaud, nearly killed Hitler. Scientific recreations and archives show their attempts against his security. New assassins would be needed to breach his defenses.

After Heydrich's assassination in 1942, Hans Oster led resistance efforts against Hitler. Multiple assassination attempts followed Stalingrad's fall, including the Brandy Bomb plot. Tests show the bomb would've succeeded with better fuse.

By now Hitler's Bloodhounds, the secret police and investigators, are hot on the heels of the resistance, some resistors are caught, tortured others are executed by the guillotine or hung on meat hooks in the notorious Plotzensee prison in Berlin. We follow the buildup to the 20th July Plot in 1944 and investigate in detail the location of the bombing attempt on Hitler at the Wolf's Lair in Eastern Prussia. The last-minute change from the concrete bunker to a wooden cabin for Stauffenberg's meeting with Hitler was to have a significant effect on the power of the bomb used. We show that if Claus von Stauffenberg had the explosives he originally intended, had met Hitler in the concrete bunker as planned and his briefcase containing his bomb had not been moved 10 cms from where he placed it, Hitler would have died on July 20th 1944, and millions of lives would have been saved.
