Part of the story takes place in Helsinki, Finland, depicted in an accurate, realistic way as the city looked in the 1950s, though some buildings pictured weren't built until the 1960s.

While going through his trunk full of old mementos and souvenirs, Scrooge discovers a page that he remembers having originally torn from one of Lönnrot's notebooks when they met in Scotland in the late 19th century.

Upon hearing of this mythical machine that can produce grain, salt, and, most particularly, gold out of thin air, Scrooge sets out to find it.

The Ducks travel to Helsinki, where the director of the Finnish Literature Society explains Lönnrot's notes to them and the location marked within.

In the ensuing battle, Louhi manages to steal Väinämöinen's famous kantele, which holds such great power that she loses interest in the Sampo.

Väinämöinen then lets Scrooge fall from the ship and congratulates him on having made the right choice, allowing him to keep the crank of the Sampo as a memento.
