Ms. Hong takes the envelope given by the Grand Empress Dowager containing evidence of the Imperial Family's corruption to the Prime Minister, but it never reaches him. The autopsy of the Grand Empress Dowager reveals poison was the cause of death, the same toxin found in the food the Empress had given her, and as a consequence, the police arrest the Empress for the murder. Meanwhile, the Imperial Family turns their back on Sunny.

Trying to clear her name, the Empress returns to the palace to retrieve a recording device she had hidden in the Emperor's chamber.
