In the official trailer for 13 Minutes, we're brought back to WWII as a room full of Nazis stand and salute the Führer with right arms outstretched. As they cheer, the sound of a ticking clock can also be heard. A nighttime shot reveals an explosion. As the trailer continues, we meet the man responsible for the bomb. He tried to save his nation from the Führer's evil, but failed. The cruel leader survived the assassination attempt and has the man imprisoned.
The trailer for the film, which is based on a true story, then explores the man's past. Before the war broke out, we see the man fall in love, become appalled at how his countrymen target Jews, and begin devising a plan to create the bomb.
