In the near future where memories can be edited and reshaped, top memory architect Ling Chen takes it as his mission to "repair" the trauma of others, firmly believing that this is the kind of kindness that leads to perfection. He built a perfect memory of his deceased wife for himself as an inner temple. However, when he took over a felon codenamed "Isu" and tried to erase her "sinful" memory, he found an "ember" pointing to his past in the fragments of her chaotic memory that should not have existed. This discovery made him question the truth of the entire memory editing system, as well as his flawless past that was regarded as a standard. Is what he protects the truth, or is it a gorgeous and cruel cage tailor-made for him?
