Cambodia 2007 Russian businessman Plensky invites a group of students to a game, the winner of which will receive opportunities he never dreamed of. You just need to hold out longer than others on a desert island - and a fantastic career in the Plensky corporation is guaranteed. It would seem that the task is simple and understandable, and the strongest, cunning and patient should win. But Koh Nag, the Snake Island where students are dropped, is not so simple and harmless. Surviving in the tropics turns out to be more difficult than the students hoped. Meanwhile, a mysterious artifact falls into the hands of one of the players, programmer Dmitry, and Plensky’s plans collapse. A small squid figurine allows Dima to control people. Will he cope with the sudden power that has fallen on him? Will the players be able to remain human, or will fear and the thirst for victory cause them to lose their human appearance? Only the evil spirits of Koh-Nag know about this...
