Successful businessman Sergei Yermolov is driving fast to Moscow to see his beloved wife and son. An unexpected encounter with a vamp woman, a beautiful artist Amelia and her daughter Marussia, abruptly changes his life. Sergei realizes that his passion is an obsession, but he can`t resist – Amalia`s charms are too strong. Sergei`s wife, Anna, does not want to break up with her husband. This gloom lasts for eight years. Sergei's mother Antonina is completely on her daughter-in-law`s side. Together they try to understand the history of the family as soon as they understand that the origins of what is happening now, is related to the past: "Our blood is older us". The investigation leads Anna to Italy, where she finds Asya`s diary, the first wife of grandfather Sergei, and the events of the past take on a visible reality. Sergei`s Grandfather Constantine in the 20s of the last century could not resist the pressure of circumstances, and gave the girl Christina, who fell in love with him, to Chekists, though he was aware of her innocence. There is also an old legend about Radziwilla`s jewelry, which with amazing persistence again and again appear in Yermolov`s family, destroying all their personal lives. Peacefully and absolutely not frightfully the red lights of ancient jewelry flash in the hands of the doomed heroines. According to the legend, the curse will be broken only after they all gather at a direct descent of Prince Radziwill.
