In the near future where memories can be read and submerged, Ling Su, the top memory diver, makes a living by diving into the deep sea of other people's consciousness and salvaging lost memories. He is calm and professional, but trapped by his dusty past. A mysterious commission from the daughter of a business tycoon led him to the sea of consciousness of his unconscious father, Gu Yuanshan. This sea is not a calm memory bank, but a rust-colored abyss full of traps and storms. Ling Su sailed in it, not only looking for the business secrets his client needed, but also unexpectedly discovered that the undercurrent of this deep sea was leading to his own forgotten island called "Trauma".
