Deep in the taiga, where humans are a rare sight, lies the beginning of Siberia’s giant river, the Lena. The taiga surrounding the Lena’s source is like an ocean – endless, immeasurable and dangerous. But it is habitat to many forest dwellers, who go about their lives and call it home. The taiga also opens itself up to people who know and respect the laws of the forest. Our film is about the mysterious beginning of the Lena River, its rapids and dark, ancient woods.
