The conceptual trial against Erzsébet Báthory is progressing unstoppably: the countess is being accused of more and more impossible things. Meanwhile, Bethlen is surrounded by someone whom she never thought of, encouraging her to betray her. Báthory is tormented by remorse for her cruel actions, but she knows that the monster she has awakened can no longer be stopped.

In her final desperation, Báthory visits Bethlen to find out if she has remained loyal to him, but the prince sees enemies even where they used to be friends. Meanwhile, the Transylvanian-Saxon army led by Géczy goes against the Hajdús army led by Báthory, and the stake of the battle is the princely throne.
