Hunted almost to extinction, the last wild Siberian tigers can only be found in the forests of the far eastern Russian frontier—but not easily. Ecologist Chris Morgan embarks on a challenge that will fulfill a lifelong dream — to find and film a Siberian tiger living wild and free in these forests. To help him, Morgan turns to Korean filmmaker Sooyong Park, the first individual ever to film Siberian tigers in the wild. Park spent more than five years watching and waiting for a glimpse of the elusive creatures, confined sometimes for months in tiny underground pits or 15-foot hides in trees. His technique was unconventional, but produced more than a thousand hours of wild tiger footage that told the story of a three-generation tiger dynasty. During their time together, Park teaches Morgan the secrets of tracking tigers—where to look and what to look for in these vast, seemingly-uninhabited frozen forests. Eventually, Morgan’s mentor and guide leaves him to his own private quest, and it is up to Morgan to follow the tracks and markings of these giant cats, searching out spots where tigers are prone to hunt, setting up cameras he hopes will also capture a precious image of a wild Siberian tiger.
