Six soldiers and their lieutenant are on an exploratory mission a few days before the end of a training course. Unfortunately, due to a mistake, the group gets lost and accidentally ends up on French territory. The lieutenant is then faced with a real dilemma: returning to Switzerland via the nearest customs post means accepting the legal consequences—in fact, any Swiss national who crosses the border with an assault rifle is automatically considered a deserter—or returning to the country illegally through the forest, which is foreign territory and sometimes dangerous.
