In 1936, in Shanghai, Paramount was singing and dancing.
Jiang Wan, a graduate student at the School of Modern Music, became the most inconspicuous singer here as soon as she opened her eyes. She originally wanted to live quietly, but unexpectedly discovered that she had a strange ability-when she sang with a specific tone, she could make people who had died no more than seven days "speak" and recreate the memory of the last seven seconds of the deceased's death.
Overnight, she went from being a singer that no one cared about to becoming a "psychic weapon" that all forces were competing for.
The cold and taciturn police detective Gu Tingshen appears to be investigating the case, but is actually an underground party intelligence agent. He detained Jiang Wan in the police station, calling it "protection", but actually monitoring him.
Bai Heming, the gentle and elegant director of the special higher education course, pursues her crazily, but there is greed and calculation in his eyes.
When the first corpse opened its "eyes" in front of her, and when the memories of the deceased flooded into her mind, Jiang Wan discovered that her past life memories were not accidental. Every corpse in the city was waiting for her singing.
And every time she uses her ability, her lifespan is shortened by one year.
Truth, conspiracy, betrayal, faith... In the darkest moment before dawn, she will use her own life to sing the last testimony of the deceased.
