A group of young people comes to a Siberian construction site. They form a brigade, one of their tasks being cutting of a track for a power line. Different reasons made these people go to taiga and become pathfinders. One of them, a former taxi-driver Leonid (A.Kuznetsov) went to earn lots of money, Rimma (A.Zavialova) from the undivided love, the yesterdays schoolboy Constantine to find romantic appeal and adventures, and Vladimir (N.Dovzhenko) attempting to escape his shadowy past. Far away from the city fuss, in severe labor conditions and unsettled way of life, relations of these absolutely unknown to each other people gradually resume the normal course. Here many of them experience revaluation of values, others even find their love.
