Detective Travis Hurley arrives in a small town in the Australian outback. The Hotel Limbo, which resembles a rocky grotto, proves to be perfect for his very own particular type of relaxation. But he has come here to investigate a case from 20 years ago for which the only evidence is a number of tape recordings: the unsolved murder of an Aboriginal girl named Charlotte Hayes. The residents are less than forthcoming regarding the provision of information; this is especially true of the victim’s fractured family. You do not talk to a cop, especially if he is white. But Hurley, in a stoic performance by Simon Baker, knows how to wend his way in his cool car through the labyrinthine landscape of the Opal Mountains and form a bond with the cave and caravan dwellers.
