The village of Kalachi, located in northern Kazakhstan, is struck by a strange phenomenon. At certain times of the year, locals mysteriously fall into a deep sleep. So deep that some can stay asleep for several weeks. No one can find an explanation, even if the uranium mine at the entrance to the village seems to be a serious lead.
To protect their life or that of their children, some families have preferred to leave the village, but the majority of the villagers have nowhere to go. So they stay there and live a life tinged with unreality.
