It is the year 1645. A murderous war has been raging in the Holy Roman Empire for 28 years, and it shows no signs of ending. Gustav and his master have been banished from the guild of black field shearers and had to leave the Swedish convoy. In the midst of winter, they travel as simple healers through the battle-scarred lands, helping the war-weary people. However, their enemies are still on their trail. Martin is still in Saxony with his apprentice. Everything there has been devastated by the war. The winter is harsh, and the people have nothing to eat. Wolves are once again on the streets. It is hard to believe how many accidents occur. A fantastic story set against the backdrop of the Thirty Years' War.
