In this stylish Finnish drama, the secrets and desires of a family can no longer be suppressed. Mikko turns out to have a hereditary illness. Since then he has been worried. How long can he continue to run the family business that he and inherited from his father, just like his illness? And how does he tell his teenage daughter and adult son that they might have the wrong genes? The imaginative eight-year-old Lumi, adopted from China, also cannot get away from her roots.

Centuries in the future, world's freshwater supplies are running out. Wars are waged over water, and China rules over Europe, including the Scandinavian Union. Far in the north, young woman, Noria, is learning to become a Tea Master, like her father. Tea Masters alone know the location of hidden water sources, including the natural spring that Noria’s father tends, which once provided water for her whole village. After her father dies, the military moves in to watch over the village -- and Noria. Refusing to give in her freshwater spring, Noria digs in deeper into her family’s secret. Within the Tea Masters’ books, she finds information that the government’s power is based on lies, that there still might be fresh water left for everyone. She risks her own life and sets out on a dangerous journey to find out if this is true.
