Seven months of filming the life of brown bear cubs at Kuril Lake in South Kamchatka resulted in a movie that plunges viewers into the wild beauty of nature and approaches a boundary beyond which man should not venture. Music, the sounds of nature, and the absence of human voices evoke nature's presence among volcanoes, rivers, and wild animals, an atmosphere of natural balance that remains in protected areas, stirring a deeper desire to investigate and conserve what we still have. The film showcases the world of nature that lives according to its laws but is open to those who enter it with respect and knowledge.
