Lu Shen is a top criminal psychologist, but he suffers from one-week anterograde amnesia - his memory is cleared every seven days.
His only clue is a note left by his "past self": "Follow the 'Dream Maker' case. The murderer's codename is Lighthouse. Be careful with the mirror."
Four dead people, four "perfect suicides", each scene contains a sense of ritual that only the murderer understands. Lu Shen relied on his remaining professional instincts to piece together the truth among the ruins of memory. But he gradually discovered that every step he took was accurately predicted-those "clues" seemed to be traps laid by the murderer himself.
Until he found a wall in an abandoned factory: it was covered with his action tracks for seven cycles and more than 200 days. In the center of the wall is written——
"D, welcome to your memory maze. Do you want to know who you really are?"
