In Xinhai City, memories can be repaired or deleted just like data. Lin Mo, a top memory restorer, can sneak into other people's minds to repair the broken time, but his own past is completely blank, leaving only a recurring lighthouse dream. One day, a mysterious woman named Xiao Lan brought an impossible commission: to restore a memory that was officially recorded as "non-existent". When Lin Mo dived into the depths of her chaotic memory, he was horrified to find that the lighthouse that only belonged to his dream actually stood among the ruins of her memory. In order to explore the truth, he stepped into a huge vortex intertwined by technology, lies and power, but he did not know that every step brought him closer to the secret buried by his own hands that could destroy everything.
