Predominantly slow-moving, energy-conserving koalas are not exactly well-equipped to handle speeding traffic and packs of dogs, or the consequences of encroaching urbanization around Brisbane, Australia. Their once quiet lives are now filled with social pressure, conflict, disease, overcrowding and the external stresses of living in the middle of what amounts to an alien world.The film explores the day-to-day dramas of urban koalas, seen through the eyes of the scientists studying their every move and vocalization. Fascinating social dynamics include a mother raising her baby, territorial displays and vicious fighting by males competing for mating rights, and the surprising life and loves of "traveling salesmen," rogue males who truly play the field. New science even "cracks the koala communication code," providing insights into their basic language and social structure. Their thunderous roars are difficult to reconcile with the familiar perception of them as cuddly creatures, yet there is a great deal about them that is surprising. Viewers will get a whole new perspective after watching this film.
