The story of the film is actually quite simple: two First Classes are tasked with communicating the order to cancel the attack, and if they fail, there will be a massacre, including one of the First Class's older brother. In the course of the mission, one of the first class was killed by the Luftwaffe, and the other successfully delivered the letter, canceling the attack and saving the lives of 1,600 soldiers.
The film won the Oscar for Best Cinematography, and sure enough, it's really beautiful.
The two take care of each other on the road.
