In the late '60s, Ted Whittlemore, a radical Australian journalist, saves Nhem Kiry, soon to become known as 'Pol Pot's mouthpiece'. The consequences haunt him for the rest of his days. When the Khmer Rouge take power in Cambodia, Whittlemore watches, fascinated and horrified, as the ideals he holds dear are translated into unfathomable violence. In the intervening decades, as he tries to make sense of what went wrong, it is as if Kiry's life has become intertwined with his own.
