Marie, young inspiring actress, has just moved to a big city. one evening she is assaulted by a man. The next day she meets Eve, a young marginal and nervous woman who entails her into a nocturnal and violent maze. For one night they become "The Vigilantes".

Flanked by their two children, Simon and Adélaïde decide, like many Parisians today, to leave their two-room apartment for a quieter and more comfortable life in the country. They are seduced by a house in the middle of nature: space, a vegetable garden, a wood adjoining their garden and above all villagers who welcome them with open arms. A dream come true! 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.
