In Xinhai City, top memory sculptor Lin Mo can accurately erase painful memories for clients. He is calm and controlled, and has polished his life like a precision instrument. However, a mysterious commission completely broke his peace: a client codenamed "K" requested to delete a trivial memory about a rainy night alley, the Blue Whale Bar and an iris pendant. When Lin Mo touched this memory fragment, an inexplicable sense of familiarity swept him into the whirlpool. He discovered that this memory was not only inextricably linked to his dusty past, but also pointed to a huge conspiracy covered up by "Yongyi Technology". In order to find the truth, Lin Mo must sneak into his forgotten island of memory and face the echoes of the past that he wanted to forget at all costs.
