Lin tide, the daughter of a genius perfumer, inherited an unspeakable "curse" - absolute olfactory memory and synesthesia. Thousands of scents will never fade in her mind, and every scent is an unforgettable image. Her father's unjust death made her choose self-exile and live in seclusion in a corner.
An impeccable murder case of a secret room doctor forced Detective Qin Feng to knock on her door. There was no flaw in the scene, except for a strange smell. From the undertones of decaying herbs and desperate anxiety pheromones, Lin tide sketches a completely different portrait of the murderer: not a calm acquaintance, but a lonely soul destroyed by illness and illegal drugs.
The truth is turned upside down by her nose. She was also involved in the whirlpool and found that the clues of her father's old case were quietly intertwined with the odor molecules of the new case. A ghost criminal, codenamed "Shadow", who is proficient in scent manipulation, whispers in the shadows of the city.
From then on, Lin tide became the most special "odor consultant" in the police station. She will peel off the only "portrait" that points to the truth from the chaotic atmosphere of blood, lies and desire. This is not only a pursuit to clear the name of his late father, but also a silent war using the most sensitive sense of smell to fight against the deepest darkness.
