In the botanical garden of an old university town in Germany stands a mighty ginkgo tree. For over a hundred years, it has been a silent witness to three life stories unfolding across generations. In 2020, a neuroscientist (Tony Leung Chiu-wai) from Hong Kong begins an unexpected experiment with the tree while researching the origins of consciousness in infants. In 1972, a young student (Enzo Brumm) is profoundly affected by a quiet encounter with a geranium. In 1908, the university's first female student (Luna Wedler) uses photography to discover hidden structures in the plant kingdom—patterns that point to a deeper order. Three tentative approaches, each firmly rooted in its own historical context. What connects them is a silent force: the persistent, mysterious workings of nature.
