Writer and adventurer Will Millard visits the Korowai four times over the course of a year, to see if he can get closer to them than is usually possible, to better understand the pressures they face as they leave the forest behind and transition into the modern world. He also wants to find out how much of their traditional hunter-gathering lifestyle still exists. What he finds shocks, surprises and confounds him, as he witnesses the last gasp of an ancient way of life which once defined us all.
