The film is set during World War II. After capturing the "trophy" Mercedes, a group of scouts, disguised as German officers commits a daring raid behind enemy lines (the 116th Motorized Division) on roads controlled by the enemy.
In the mountains, they stand alone against whatever will happen. For the several days they live in nature, they can rely only on themselves and each other. Elsewhere, there is always a fallback - here one is without a safety. This in itself can bring some to terror - the terror of having to rely on yourself - your own judgment, wits and fortitude. This is also the most incredible feeling of strength and independence. Knowing there is no safety means having to be one's own safety.
