Driven by a determination to combat desertification, a crisis predicted to claim 90% of the planet's land by 2050, landscape architect Louis De Jaeger embarks on a 7-year mission to transform a dune into a food forest. The documentary captures the grit and ingenuity required to regenerate soil and create sustainable ecosystems. Through innovative techniques like nutrient recycling, composting, and using "weeds" as free fertilizers, Louis turns infertile sand into rich, organic soil, supporting a productive food forest.
