In 1648 Kilian van Roggenburg and the Jesuit Pereira set out with a group of men to find a new land route to China for, among others, the Fugger. Their journey is perilous and they must regularly fight the savages. Kilian's son, Wolff, also falls in love with the Siberian girl Nadja along the way. It remains to be seen, however, whether the group will ever reach their destination.
