In the film, we accompany a biologist responsible for the implementation of renaturation solutions, the most coherent with the activities already present in the field. A series of hedgerows planted to ensure bocage continuity is a typical means of providing food and shelter for small mammals involved in an ecosystem that includes cultivated fields and wild lands. Compromises are made to allow continued passage with farm machinery. The viewer discovers that it is possible to observe significant changes in biodiversity if one is attentive to the smallest phenomena, such as the return of butterflies that had disappeared. Through the testimonies of involved farmers, we learn that synergies between animals, plants and farms increasingly make it possible to do without chemical substitutes, those that have long accompanied the productivist approach on which agriculture is still largely dependent. From the scouting in the middle of winter, to the informal meetings between participants discussing in the middle of the heat wave, the film shows from the inside an experience of active awareness but not without its paradoxes, particularly how to reconcile issues as remote as profitability and biodiversity.
