Chen Mo was once a genius criminal investigation portraitist, but now he is a patient imprisoned in the cage of his own memory. A tragedy caused him to lose everything, and he suffered from hyperamnesia that he could not forget - every detail, every moment of pain, was forever looping in his mind.
Until a bizarre suicide case forced him to look back on the past. In a closed study room, a successful entrepreneur committed suicide by "suicide" with extreme fear on his face that was completely opposite to his personality. At the pleading of the police, Chen Mo reluctantly touched the body——
In an instant, he "saw" the last memory of the deceased.
However, that memory is not that of the deceased. Through the eye holes of a cold clown mask, he is watching the passing of life indifferently. The killer isn't erasing memory, he's stealing it.
When the second and third "suicides" occurred one after another, Chen Mo was horrified to discover that the murderer, who called himself "The Clown," was using killing as a pen to steal the most extreme moments of other people's lives to build a twisted and gorgeous "memory gallery." What is even more chilling is that in the final memory of a deceased person, Chen Mo saw the person he wanted to protect the most - his niece who had lost her memory due to trauma, being quietly peeped by the clown outside the window.
This is a hunt for the nature of memory. Chen Mo must use his ability that is both a curse and a gift to penetrate into the memory maze carefully woven by the murderer. But as he gets closer to the truth, the boundary between reality and illusion becomes less clear. Until the clown whispered in his ear with a mocking voice:
"Share my collection with you. Do you also feel that other people's memories are more real than your own?"
