In the neon and rain-shrouded future city - New Arc City, memory is both a commodity and a weapon. People can share experiences and back up their lives through the "memory web", but at the same time they live in fear of being spied on and tampered with.
Ling Su, a highly skilled but mentally frozen memory weaver, specializes in salvaging the truth from the chaotic ocean of other people's memories. He makes a living by repairing memories, but is unable to piece together his shattered past.
When a mysterious plague called the "Forgotten Tide" spreads throughout the city, and people begin to forget important history, close people, and even who they are out of thin air, Ling Su is involved in an unprecedented conspiracy. A ghost codenamed "Wuhen" is trying to erase a taboo history related to the city's survival from everyone's minds, and promises a "pure white rebirth" without pain.
Forced to join forces with elite agents within the system, Ling Su pursued "Wuhen" in the maze of virtuality and reality, but step by step he walked towards his own dusty nightmare. When the truth of history is revealed, the pain is far beyond imagination.
Should you choose to embrace false happiness or protect the cruel truth? In the final battlefield of memory, Ling Su must make a choice, and his choice will redefine the soul of the city and himself.
