2046. The air has become unbreathable and the planet is suffering from a lack of oxygen. Green Militias are in power and have been denying people all contact with Nature for years in order to heal it. In NUR, in Sardinia, stretches one of the few remaining surviving forests, bordered by an impassable wall and guarded by drones. Five teenagers, who grew up without ever having touched a tree or taken a swim in the sea, decide to enter the forest, risking their lives, to discover the truth about their parents’ disappearance and take back their future.
