There was only eight hours, limited weapons and ammunition, and no one knew the enemy situation ahead: a deadly silent land, barbed wire full of corpses, sudden enemy troops, and dangerous situations that could kill at any time... This time, the two teenagers had to save 1,600 lives, and they would rather die than not complete it!
