Who can you trust in a country haunted by its past? On the hunt for an abducted Indian beggar girl, Peruvian National Police officer Nina Flores is determined to track down the suspected kidnapper, a man who resembles what the locals call pishtacos: tall, pale ghosts who steal children. In spite of being jumped by a mysterious attacker, and the murder of a woman who gets too close to the truth, Nina is blocked at every turn by her superiors. Then she discovers links to a second case reaching back twenty years to the country's dirty war. Defying the powers that be, Nina forms a shaky alliance with a member of a brutal drug cartel and heads deep into the Amazon jungle. She will bring the lost one home, or die trying.
