Shortly after the Thirty Years' War, a former soldier arrives in a remote Protestant village, claiming to be the legitimate heir to a long‑abandoned and ruined estate, and he confirms his rights with a document. At first, the villagers treat the soldier with distrust, but gradually he earns the respect of his neighbors. However, the new resident’s position is based on deception: in reality, his name is Rosa, and he is a woman who has assumed the identity of a soldier who died in the war.
