On a cold winter day in 1940, little Jules and his family move to live with his uncle Jovite, mayor of a village in northern Quebec. Because of a rare disease he suffers from, he quickly finds himself banished from school. His dog then becomes his only friend. But when the latter flees into the forest, Jules has no choice but to venture there to find him. Along the way, he meets Asha, a mysterious little girl who assures him that her mother could completely cure him of his illness. The problem is that she doesn't know where she is. Together, they decide to go looking for her, but what is at the other end of the forest is not what they had imagined.
