August 21, 2015. After a wonderful holiday in Italy and Germany, three American pals take the train to Paris. During this period, an armed terrorist enters his wagon and endangers the lives of the 500 passengers on board. The Americans are trying to defeat him, but no one would have imagined that Spencer, Alek and Anthony will find themselves in an inappropriate place at an inappropriate time. Not even two of them are actually military. Or that during high school there were turbulent students subscribed to the director’s office. But as they age, they became heroes.
