Finnish hero Lemminkäinen woos the fair damsel [[LoveInterests Annikki]], but an [[WickedWitch evil witch]] named Louhi kidnaps [[DistressedDamsel Annikki]] in order to compel her brother Ilmarinen the blacksmith to build a Sampo (a magical mill that cranks out riches). Lemminkäinen and Ilmarinen travel to the witch's lair to rescue the maiden, but Louhi demands them to complete several tasks, including the construction of a Sampo. After Ilmarinen builds the Sampo, he and Annikki leave Lemminkäinen behind while he tries and fails to get the Sampo from Louhi [[NiceJobBreakingItHero and destroys it]]. When Lemminkäinen returns home, he and Annikki get married; the mood is offset, however, when news of the Sampo's destruction arrives.

Lemminkäinen's attempt to steal the Sampo has angered Louhi, so she steals the sun, [[TheNightThatNeverEnds plunging the world into frozen darkness]]. Lemminkäinen's village bands together to bombard the witch with the music of sacred harps, which [[TakenForGranite turns her to stone]]. Lemminkäinen releases the sun and [[HappilyEverAfter everyone rejoices]]!

Loosely based on TheKalevala. The film was originally called ''Sampo'' and it was released in 1959. The film was produced as a Finnish/Soviet co-production and it was directed by famous Russian director of fantasy films, Aleksandr Ptushko (of ''[[Film/{{Sadko}} The Magic Voyage of Sinbad]]'' and ''[[Film/IlyaMuromets The Sword and the Dragon]]'' fame). It was filmed in Ukraine, Finland and Russia and starred actors from Finland and different parts of the Soviet Union.

Not to be confused with ''TheDayTheEarthStoodStill''.

!!This film provides examples of:

* BigGuy: Ilmarinen
* {{Bishounen}}: Damn, Lemminkäinen is pretty.
* BlackCloak: Louhi's trademark, but Lemminkäinen's mother wears one as well (maybe not regularly though, since she was in mourning believing her son was dead).
* DistressedDamsel: Annikki
* ExecutiveMeddling: As was typical in this era the cast and credit names are anglicized to obscure the films’ foreign origins. The only one accurately credited is the story's author - Elias Lönnrot - and they even removed the umlauts from his name!
* GhibliHills: Before the Sampo is taken away and after it returns, the scenery is quite idyllic.
* ImpossibleTask: Louhi demands that Lemminkäinen plow a field filled with [[WhyDidItHaveToBeSnakes thousands of snakes]]. This does not aid her goals in any way and is apparently for her own amusement.
* Literature/TheKalevala: The movie is based on one of the stories in it.
* LoveInterests: Lemminkäinen and Annikki
* MagicMusic: The method used to defeat Louhi
* MythologyGag: The film begins with a shot of a statue of Elias Lönnrot and Impi (symbolic of the poetry of Literature/TheKalevala), which [[LivingStatue magically come to life]]
* NiceJobBreakingItHero: Lemminkäinen and his attempt to retrieve the Sampo
* PublicDomainArtifact: The Sampo
* SceneryGorn: After the Sampo is taken, the land looks a lot less pretty.
* SupervillainLair: Louhi's island.
* TakenForGranite: Louhi's final fate; she gets broken into hundreds of pieces by Lemminkäinen immediately after
* UltimateBlacksmith: Ilmarinen can make [[AutomatonHorses a horse out of iron]], a moose-boat the same way...even a Sampo! After the endless winter begins, Lemminkäinen actually convinces Ilmarinen to start forging a new sun although Väinämöinen talks him out of it.
* WickedWitch: Louhi
