In a future city where memories can be accurately deleted and sealed, top memory architect Ling Chen makes a living by stripping away the pain of others. He is calm and efficient, just like the sterile cabin in which he works. However, when a woman named Xiao Ran appears with a strange request - to find a forgotten "security" - Ling Chen's orderly world begins to collapse. After diving into Xiao Ran's sea of broken memories, he found that those scattered fragments echoed the most painful past that he had sealed long ago. Every island of memory he explores brings him one step closer to the truth that can overturn the fate of two people, and also makes him fall into a whirlpool from which there is no turning back.
