Leader (1980)

A group of geologists was landed in the taiga. But the guys can’t work - they gave them the wrong bits for the equipment by mistake. And the radio doesn’t work, and the helicopter is expected only in two months. And the squad leader, a young guy named Dmitry Alekseevich Ryabtsev, makes a decision - he alone goes to the nearest detachment. By taiga standards, this is not far - 20 kilometers. But when he returns, he discovers that his squad has left the camp.
