In Isère, in the mountainous region of Trièves, is the Tournesol farm, an experiential farm totally autonomous in energy, a veritable laboratory for renewable energies. Jean-Philippe and his family live there from sheep farming and organic market gardening. But in September 2017, a violent fire destroyed the farm and its facilities. While the family has lost everything, a surge of solidarity is taking place so that the Tournesol farm is reborn from its ashes.
