Based on Finnish mythology, this movie traces the exploits of Lemminkäinen as he woos the fair Annikki and battles the evil witch Louhi. Louhi kidnaps Annikki to compel her brother to build for her a Sampo, a magical device that creates salt, grain, and gold. When Lemminkäinen tries (and fails) to recover the Sampo, Louhi steals the sun, plunging the world into frozen darkness.
