In Quebec's Kamouraska Valley, Patrice Fortier is putting down roots at his seed company, La Société des plantes. Like a copyist in the Middle Ages, he is meticulously preserving rare and forgotten cultivars with the goal of breeding the "heirlooms of the future". As Patrice gardens, he daydreams and transforms his harvests into art projects. The seasons come and go, his patience and care express his passion and knowledge, and his seed bank grows. His tiny storehouses of life will eventually sprout in thousands of vegetable gardens around the world. At the center of this paean to plant biodiversity and agricultural heritage is a unique, genetically motivated seed producer. Watch: the impossible is underway.
