Shen Du, a former professor of criminal psychology, lost all his case files and colleagues in a fire and was selected by the "Crime Museum". He is calm and rational, but deep down he is obsessed with "unfinished" - he believes that every unsolved case is an unfinished question and someone must finish it.
There is a "Crime Museum" in parallel time and space - all unsolved unsolved cases will be embodied as "exhibits" here. Each exhibit is an independent space, retaining all physical traces and "emotional residue" of the crime. The protagonist is a "recruited" museum administrator whose task is to enter the exhibit space, interpret the traces and emotional residues of the scene, restore the truth, and solve the case.
