But the young couple was soon to be disillusioned: the wood was actually a hunting ground for big game! Although the hunters are friendly, they are not willing to give up their territory, making Simon and Adélaïde's dream of the countryside a living hell. But true to their reputation, our Parisians are not going to let them do it.
