Ten years ago, young artist Shen Yue disappeared mysteriously, and the case was summarily closed by the police. Gu Huai, a promising detective, was burdened by the case and eventually resigned from public office. Ten years later, a painting signed "Yue" suddenly appeared at an underground auction. The details in the painting were strikingly similar to the style of Shen Yue's works, but it also contained a strange twist. This painting is like Pandora's box, pulling Gu Huai back into the vortex of the old case that has been dusty for a long time. He discovered that Shen Yue's disappearance was not only a fragment of memory, but also involved a huge network of power, desire and lies. In the process of reconstructing the truth, Gu Huai not only had to face numerous resistances from the outside, but also faced the forgotten fear and guilt deep in his heart, as well as the struggle and redemption of human nature in desperate situations. This city may seem glamorous, but in fact it contains countless broken memories, and Gu Huai is destined to piece together the deliberately tampered reality in these ruins.
