Toivo’s blood is exceptionally powerful. When the Finnish ski team hears about Toivo, they understand they have found a highly prized secret weapon. His blood can improve any athlete's performance, fueling the skiers to success. The prospects are fantastic, and in particular, Toivo works closely with one of the most talented of the skiers, Aino.
It is the 1980s. Toivo is an unemployed typesetter. His wife Pirkko encourages him to do something useful, so he goes to donate blood. The blood astonishes the hospital nurse who assists him. The Finnish national ski team then discovers the special qualities of Toivo blood, and soon Toivo joins the team’s technical division to take up his secret role as a human blood-tank.
Finland's brightest star is making a breakthrough: Aino. A young woman, Aino is not only a good skier but an impressive public brand, with the nickname Finnmaiden. Soon, Toivo and Aino become an integral pair.
With Toivo's help, Aino skis to the top of the world rankings. Just before the most important race, however, a disaster occurs, which jeopardizes the highest goal: Olympic victory. Once again, the Finnish team’s success is placed in Toivo’s hands.
Will the dangerous plan succeed? What will Toivo do? What will happen to Aino? And most important of all: Is Toivo a patriotic man?
