Increased travel to the moon Volka in recent years has led to drastic changes - miners have been plundering the mineral deposits, trappers have been removing animals from their zones and ancient artifacts are being removed or broken. Chubbsel and Chubsuki are on a camping trip to the moon. When exploring an ancient site, they hear an emergency siren, but whilst they are trying to leave, their vehicle breaks down. They are rescued by head ranger, Bujac, who takes them to the nearest campsite. But when disaster strikes the camp, and the campers are left with no communication with the outside world, they must make their way to safety. When its minerals, creatures and relics are taken from where they belong, the world shifts quietly at first - until the cost of that change becomes impossible to ignore.
