年轻的语言学家深入南美文明腹地，在热带雨林中寻找一种叫Zikril的语言。当地只剩两位男子会讲这种濒临灭亡的语种，但他们已经整整五十年没跟对方讲过话。在语言学家挽救语言的同时，一段禁忌感情也被唤醒，半个世纪的爱恨穿过时光的长廊，在烟消云散前最后一次复燃……

The earth has stopped spinning and days have stopped passing by. One toxic, dense fog covers the forest immersed in eternal twilight.
Argel has spent his life, with his two siblings, locked inside the basement of an old cabin. They believe that a wild beast wanders in the forests depths. When his older brother mysteriously disappears, Argel undertakes a quest which will cause him to break the order and the rules with which he has grown up.
Little by little he will discover the darkest secrets and mysteries that both his father and the forest hide.
