Sarah, a young American, convinces her three friends - Isaac, Jackie, and Horacio - to assist in completing her audacious ecological documentary. Their journey takes them deep into the shadowy world of illegal mining in an enigmatic Peruvian forest. Upon arrival, locals vehemently caution them against approaching the forest or the mining town, citing the presence of the Supay - an ancient being from Andean mythology capable of taking various forms and remaining unnoticed to attack intruders. The Supay has claimed the area and eradicated the miners for bleeding the earth. Initially dismissing these warnings as ploys to conceal illegal activities, the group defiantly breaches the prohibition, venturing into the forbidden territory. However, they swiftly realize the chilling myths hold genuine and terrifying truths, along with the actual purpose of their presence - a revelation that will forever alter their fates.
