A rich widow is found dead in her apartment in Helsinki due to gas poisoning. The incident is initially thought to be an accident, but inspector Palmu notices that the murderer made a mistake, and so Palmu, Kokki and Virta begin the investigation: who had come to the apartment through the balcony door and opened the gas tap while Mrs. Skrof was asleep?
A man's body is found on Tähtitorninmäki in Helsinki. Palmu starts to investigate the case, but the scandalous newspaper story causes problems for the police.
Täällä Pohjantähden alla is based on the book with the same title. It is a story of the little village. The movie starts in the 1890's and it ends to the Finnish civil war in 1918. Story concentrates around a tenant farmer family, although it gives us a good look at the society at whole. While the class struggle depends, people of the village are driven to bloody civil war.
