In a botanical garden, a tree watches and observes, a patient witness of centuries. In 1908 he follows Grete, who struggles to survive in an environment that ignores her. In the 70s he sees Hannes awaken to love and the world of plants. Today the old tree speaks with Tony in his secret language. Around him some search for themselves, others meet each other. He remains, like a silent friend, in a time that is greater than theirs.
