Looking for the title of the Scandinavian film. Set in 1920-30, filmed in 1990ish Plot: Young girl of rich parents, about 10-12 years old, fakes her own kidnapping. She hides herself in the city sewage system, where she meets a man who cleans the sewage. Mentally and intellectually she is more mature than this man, who gets bullied even by his own colleagues. She uses underground sewer system to withdraw the ransom money, instructing police to place it near the drain grill. After moneys are obtained she takes man to the best hotel and gets him dressed in the best suite. Finally girl gets ill and man bring her back home.
Thank you.
