The story takes place in the mountains of Tusheti (Northeast Georgia) where a shepherd refuses to obey his rich and influential master.

A group of young geologists will try to explore the Tsani Gorge in the Caucasus Mountains. But the geologists lack the experience of mountaineers and their attempt fails. The geologists organize a hike again under the leadership of experienced mountaineers, young engineers - Osiko and Tite. The geologists are on the top of the mountain to determine the thickness of the ore layer. Suddenly, a storm breaks out. To save the geologists in danger, a rescue squad sets off from the mountaineering station. The geologists carry out their task and return safely.
