1930. Augustin Rivard pursues a great dream passed down from generation to generation: to exploit the vast family sugar bush to its full potential. Under the watchful eye of his father, the young man does not count the hours and gets down to the task with ardor. Soon, the lovely Marie-Laure, for whom her heart beats harder every day, shows her her feelings. After some reluctance, he decides to get involved with her and gradually involves her in his ambitious project. The entire clan is working to make the business prosper. Indispensable, the women of the household get their hands dirty: Marie-Laure and Beatrice, Augustin's mother, have the idea of preparing meals for visitors. Quickly, success was there and the dining room of the small wooden cabin had to be enlarged. As the years pass, the couple's children help perpetuate the tradition. While Edward prefers to take care of the fields where he grows wheat, oats and hay for the animals, Henri knows instinctively which trees to cut to develop the paths and makes, like a wizard, the best syrup. of the region. But the boy suffers from a terrible disease, considered by many as an intervention of the Devil, which upsets those around him. The vagaries of nature, the slander of the villagers and the disease will they endanger the success of the Rivard sugar shack?
