Grey Bear (1988)

In the Siberian taiga there lived an old medic-herbalist. Once on her porch they threw a small child in a basket. When the boy Vanya grew up, he began to help look for grass in the taiga. Somehow he went for herbs and met a Bear with a bear cub. It turned out they can turn into people, going around the magic spruce. Years passed, the guy grew up and became a doctor himself. He also protected forest animals from hunters. And again he met a Bear and a bear cub.
