The world's forests get their own chapter in this nature documentary, moving from the Siberian taiga to temperate woodlands to show how tightly the pieces of a forest ecosystem depend on each other. Wild boars root through pine cones on the forest floor while a Siberian tiger stalks them unseen, a predator-prey sequence used to illustrate how removing one species from a forest can unravel the whole web around it. Bald eagles appear as another thread in that web, hunting along forest edges and waterways. The film also follows the people living alongside these ecosystems, including hunters and their dogs working the same ground the wildlife depends on, and sets their presence against the pressures of logging and a warming climate that is shifting where these forests can survive. Footage stays close to the animals themselves, letting behavior rather than narration carry most of the argument about what resilience in a forest actually looks like, and what happens when it starts to fail.
