Detective Francisco Bermejo, of the Madrid Police Department, Spain, worn down by his personal demons, takes on a seemingly routine case: the disappearance of a young couple during a day out in the mountains. But the discovery of their lifeless bodies positioned in peculiar and symbolic scenes turns the investigation into a nightmare. It soon becomes clear that a methodic and merciless criminal is at work. The macabre clues left behind seem part of a psychological game, one that challenges the investigators at every turn.
