Off the coast of Central Africa lies an isolated island, covered by primeval rainforest and surrounded by dark ocean waters, inhabited by a greater variety of species than nearly any other place on Earth. This terra incognita is called Bioko. The ruler of this realm is one of the world's least known primate species, the drill. This film explores the secret lives of these, including the nesting grounds of various sea turtles and the rugged caldera. We follow Motuku, an alpha male, and his family. The newest member of the group is little Sipoti. Over the next few years he will learn the intricacies of the drill society – something researchers will be learning with him as little is known about this monkey species. Perhaps he’ll someday become an alpha and rule over his own rainforest kingdom on the island.
