Ten years ago, a fire destroyed Yu Ning's family and past, turning her into an ordinary survivor at the bottom of the city. Until a blood-stained letter breaks into her life, and the words "Game of Death" drag her back to the deliberately forgotten disaster - it turns out that there are undiscovered secrets hidden behind the fire, and she is the key to solving the mystery.
In order to find out the truth, Yu Ning stepped into an abandoned factory, but accidentally encountered mysterious black shadows and strange symbols, and realized that she had already been involved in a puzzle controlled by unknown forces. As the investigation deepens, she discovers that the fire ten years ago was no accident, and involved power, conspiracy and more covered-up victims. Every step closer to the truth is accompanied by a fatal threat; every new clue that emerges points to a more complicated past. In the game of survival and revelation, Yu Ning must deal with surveillance and pursuit, piece together broken memories, fight against enemies hiding in the dark, and finally uncover the truth of the "death game" and seek justice for herself and those who have passed away.
