Overview:Among the forests and ruins of Madagascar's Berenty Reserve, four gangs of ring-tailed lemurs are locked in a feud over territory, resources, and power... and often the fiercest conflicts are happening within the tribes. This five-part series places you in the heart of "Lemur Island," where half of the world's wild population of lemurs share a fragment of land less than a square mile. Here, battle lines are drawn and crossed, leaders are trusted and tested, and gang members thrive or perish in the harsh extremes of this intense environment.
