In the near future, memories can be read and repaired. "Memory Submarine" Lin Mo can sneak into other people's broken mental images and salvage the lost fragments. He is calm and self-possessed, but is troubled by a memory gap in his childhood. When business tycoon Chen Bosong entrusted him with a huge price to find a memory of his first love about a mysterious female pianist, Lin Mo thought it was just an ordinary mission. However, as the submarine went deeper, he discovered that the depths of Chen Baisong's memory were not romance, but a prison built of guilt and fear. What made him shudder even more was that the echo of that island of memory had a fatal resonance with his own lost past.
