Plot Summary:Follow individual koalas from a small social group on an Australian island to learn just how a koala manages to survive and thrive on a diet poisonous to almost all other herbivorous mammals. From the miracle of marsupial birth to tender moments of discovery between mother and newborn joey, encounters with threatening forest creatures, battles between rival males and the complex chorus of bellows and grunts that have become so important to science -- join leading scientists as they unravel just what a forest needs to support a healthy population of koalas by listening to these marsupials themselves and cracking the koala code.
As cameras follow a family of koalas on an Australian island, a look is taken at the herbivores' unique bond with the eucalypt trees, and while the plant is poisonous to most other mammals, the marsupials rely on the trees for mating, food and more.
