Evelyn, a royal‑court perfumer, was burned at the stake after being blinded for uncovering the hideous secret of favourite concubine Isabel. Five years later, her younger sister Cecilia enters the palace as a low‑ranking maid. She embarks on her path of vengeance by relying on her perfume‑making skills, feigning weakness, winning imperial favour, and leveraging the underground servant network.
She first eliminates Dubois, then contends with Marguerite and Valeria. In the end, she exposes Isabel’s heinous crime of using young girls’ blood to preserve her youth, and has her imprisoned in the Black Tower. Cecilia ascends to the throne as Queen, securing justice for her sister and all the oppressed common folk.
