In the year 1595, following the brutal war between Finland and Russia, brothers Knut and Erik are part of the commission marking the border between the two countries. In doing so, they commit a terrible sin and must survive the consequences. They can only find solace in a sauna where all sins are washed away. The film marks director Antti-Jussi Annila's follow-up to the TIFF06 film, Jade Warrior.
