In the near future where memories can be stripped, stored and cleared, Ling Zhou is a top "memory cleaner". With scalpel-like precision, he erases the painful past for his clients, while he seals his emotions under cold rationality in the isolation of his profession. During a mission, he encountered a forbidden memory called "Whale Drop". After the erasure failed, this fragment of memory invaded his consciousness like a virus. A deep love that does not belong to him, a strange sea, and a recurring name drag him into a huge mystery. When the reality he lives on begins to collapse, Ling Zhou must trace the source of this memory and face a truth that can overturn his entire world.
