A patch of land in Cornwall becomes the test case for a simple question: how much of daily life could a garden actually supply? The film walks through the Plants for a Future project, where researchers and volunteers catalogue species that can be eaten, worn, burned as fuel, used as medicine, or built into shelter, rather than grown purely for looks. Interviews and on-site footage show the plants themselves, unfamiliar leaves, roots, and shrubs sitting alongside the vegetables most gardeners already recognize, and explain what each one yields and how it's used. The project's scale is modest, but its ambition is not: a working demonstration that a temperate-climate garden can function as a self-sufficient resource base rather than decoration. The film stays close to the ground, favoring practical demonstration over narration-heavy argument, and lets the sheer variety of uses make its case. It's a quiet look at permaculture thinking applied to one real piece of land.
