Mountain fantasy (1972)

Indigenous people of north have an old legend about the mountain of stone idols Man'-Pupy-Nor. Once upon a time giants-man eaters invaded the land of mansi. They went and devoured everything on their way. But then the sky split into lightnings and villians belt-dropped into the ground turning to stone. Their copper shields and giant maces decorated with diamonds are still laying somewhere near covered with leaves and overgrown with wild herbs.
