The Philippine tarsier is barely six inches tall, weighs about as much as a deck of cards, and has eyes so large that a human proportioned the same way would have eyes the size of grapefruits. It survives only on a handful of southern Philippine islands, and this film settles on Bohol, where more than 1,200 limestone mounds known as the Chocolate Hills rise out of humid forest that the tarsier has occupied for something like 45 million years. Nocturnal and solitary, it hunts insects by sound alone, swiveling ears that move independently of its head, and gripping branches with elongated fingers built for a life spent almost entirely off the ground. The film follows local biologists and villagers who track its habits, including a mating window that narrows to a single night each year, and traces how a species long dismissed by islanders as a bad omen has become the subject of a dance created in its honor. Bohol's shrinking forest, and what that means for an animal already reduced to a few pockets of island, sits under the whole film.
