The young noblewoman Elena arrives at the castle in Sokolice to marry a powerful count. But her heart is more drawn to his son Gabriel, whom she has known since childhood. However, the handsome knight didn't come to his birthplace just for the wedding. No one knows that he has been commissioned by the king to expose a traitor supporting a heretical movement. Elena thus unwittingly puts herself in danger, both in matters of love and life. The intrigues of Gabriel's fiancee Juliana and a hidden enemy threaten to drive her straight into the arms of death. Apart from Gabriel, he cannot trust anyone, and there are several suspects of treason, led by Count Sokolický himself... The estate is finally shaken to its foundations by its own past.
