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.

Elodie and Marie, two teenage girls in a city where the housing crisis worsens by the day, are faced with a lack of prospects offered by the future, and see their chances of independence gradually disappearing. Elodie and Marie suggest a solution more extreme than not; empty apartments unjustly occupied by the "old" that, in their eyes, are the origin of the current social imbalance. In this journey through the initiatory path of adolescence, they discover that behind their cold calculations, human beings are just as lost they are.
