Devils Tramping Grounds [Russian]

Justin convinces his friends to embark on a journey to the Devils Tramping Grounds to camp. The local lore says the Devil walks the grounds every night and those who stay are never found again. The adventure is meant to be a fun last "hurrah" before they leave each other for school and jobs. They deliberately aim for a piece of ground in the shape of a circle where supposedly nobody lives through the night. Do they survive is the storyline.
