[1] Before Rákóczi's war of liberty, during a hunting expedition, Pál Görgey, the arrogant but noble leader of the Hungarian county of Szepes, shoots Károly Kramler, Saxon magistrate of Lőcse, for having killed Görgey’s favourite dog.

When their magistrate is fatally injured, his company, on the advice of one of their members, Nustkorb, takes the still-living body and marks with his blood the boundaries of a large field owned by Görgey.

The traumatized citizens now believe that Nustkorb was killed by Kramler's ghost, who took a revenge on his real murderer.

Fabricius makes a trap for Görgey, catches and executes him - but realises too late that he was Rozália’s father.

He is shocked by this discovery; but on the streets all the folk of Lőcse are glad, singing, dancing and burning their black clothes now that the revenge has been completed.
