On the edge of a time-distorted cyber city, embalmer Lin Mo runs a "last wish agency". The mysterious system he inherited can reveal the unfulfilled wishes of the deceased. After completing the task, you can exchange for memory fragments and obtain the skills of the deceased. When Su Yan, a cultural relic restorer with a mysterious life experience, becomes his roommate, the antique brain-computer interface she repairs keeps leaking memory scenes that are exactly the same as her childhood. The two were involved in the legendary "Lost Island" that appeared periodically, and discovered that the island was actually the remains of the ancient god of memory, still breathing human memories unconsciously. Lin Mo's system is actually a gentle trap set by the gods to recover Su Yan, the "unfinished product". When the island is about to sink forever, they must make a choice: become new gods, erase the past, or turn this memory cemetery into an emotional memorial for all mankind?
