But she soon gets lost in the hostile jungle, which is rumored to be haunted by the spirits of Moro warriors who fought off conquistadors with their blades. As she tries to stay a step ahead of the terrorists and not-so-dead spirits with a taste for human flesh, Annja's not sure she'll leave the jungle alive...
