Based on the international bestselling book by German forester Peter Wohlleben, documentary filmmaker J?rg Adolph features the author in classroom lectures, direct interviews, and explorations in forests where he expounds on the tenets he put forward in his book: that trees function as humans do, as they communicate with each other, have social lives, and live in colonies that they protect and guard against enemies they could detect. Featuring nature shots directed by Jan Haft.
