Valentin Vaala's historical suspense film The Green Chamber of Linnaeus (1945) is based on the novel by Zacharias Topelius. In the story, set in the 1830s, Colonel Karl Littow, the lord of Linnainen Manor, and his daughters Anna and Ringa are proud of the immaculate history of their noble family. A foreign Count Spiegelberg, who is courting Anna, and the architect Kaarle Lithau, a minor member of the family, who is planning to renovate the building, come to visit the manor during the winter. Soon, the centuries-old secrets of the Linnainen estate and the Littow family threaten to be revealed to the estate's guests and hosts alike.
