Huge, lustrous eyes glisten in the moonlight, mobile ears scan the still night air, long elongated fingers cling to a branch and a strange whistling squeal pierces the silence of the forest. This is the mysterious Philippine tarsier.

These alien-like creatures are the oldest primate and we share a common ancestor. Inhabiting the once abundant, now diminishing rainforests in the Philippines, tarsiers were long considered as otherworldly and spiritual, and for years have been hunted by the greatest predator - man.

But thanks to the commitment of a local man there's a new glimmer of hope for these beguiling characters. This engrossing film unravels the mystery of these alien-like, otherworldly creatures, and takes viewers into the depths of the Philippine forests to witness tarsiers in their natural habitat.
