The Siberian tundra is home to the Nenets people, who live traditionally amidst extreme cold. Ten years ago, in 2010, we met Nenets children aged 7-8 there. And ten years later, how are the tundra children, now in their late teens, living? After reuniting after a decade, the children are contemplating whether to live in the city after graduation or return to the tundra. Over the past ten years, the tundra has been rapidly changing due to climate change and gas development. What choices will the children make? If the previous work depicted the story of the vast tundra nature, this broadcast unfolds a touching story of the tundra children who strive to protect their land.
