In a mystical autumn setting, the Ahr River winds its way through fog-laden forests and hills. Within this serene landscape, a man finds himself waking up in a vineyard, with no memory of his identity, location, or how he arrived there. Nearby, the lifeless body of a young woman lies among the grapevines. As an outsider in this isolated village nestled in the Ahr Valley, he becomes part of an ancient community that appears to be hiding something from him.
