Based on the actual expulsion of French Acadians from Nova Scotia in the eighteenth century, The Loup Garou recounts the adventures of Robert and his two friends, Louis and Little Otter, as the English try to force them from their homes. Having been tricked with other boys and their fathers into being taken prisoner in a church, Robert crawls through a small window to find his way back to his mother and home. With Robert's bravery, and the help of the Micmac Indians and the mysterious Loup Garou, a legendary creature who turns from man to wolf at twilight, Robert's family struggles to stay together in their homeland.
