In the future city "Hailin City" where memories can be extracted, edited and traded, Lin Mo, a top memory restorer, spends his days mending the broken pasts of others, but he is unable to piece together a key memory that he has lost. A mysterious commission draws him into the whirlpool: a memory fragment full of violence and sadness that does not belong to her appears in the mind of the socialite Su Wan. When Lin Mo dived into that memory, he saw his young face in the reflection of the cold rain alley. Why does his past become a nightmare in other people's minds? On this island of memory surrounded by the sea of oblivion, truth and lies are intertwined. Every exploration is a cruel interrogation of self-existence.
