Things are tense between Thomas and Marianne. To give their relationship one last chance, Thomas borrows his uncle’s cabin for a weekend in the country. There, they meet Ben, a neighbour, and hang out with him. Unfortunately, the weekend doesn’t have the desired effect. Absorbed in their own squabbles, the couple fails to notice that Ben is not who he says he is. His real name: Jean Messier, and he isn’t his uncle’s neighbour… Who is he? What does he want? When the weekend is over, Thomas and Marianne head home sharing a dark secret.
