In a secret room at Xinghu Bay Villa, the singer Su Wan is found dead in an apparent "suicide." When memory technician Lin Ye extracts the final 30 minutes of her memories, he sees the same red floral pattern as at the scene of his mother's "suicide" all those years ago. At last, he has a clue to the mystery that has haunted him for ten years.
The Memory Replay Bureau's Recall Device can peer into the secrets of the dead, but no one knows it can also steal the extractor's memories in reverse. As a string of murders points to the "Reflux Project" from ten years ago, his partner becomes a suspect in an inside job, and the director's gun points at his temple, Lin Ye finally understands: he is not investigating the cause of his mother's death, but a terrifying truth hidden in everyone's memories, one capable of turning the entire city upside down.
