In the new Shanghai of 2089, sleep is the most luxurious commodity. Lin Mo is the top "dream hunter" in the industry, specializing in sneaking into the subconscious of dangerous people to steal secrets. He never questioned the mission until that day, when he saw his childhood memory in the dream of the drug lord Carlos - the vague woman humming a lullaby, which should only exist in his private memory.
When memory restorer Ye Lan dragged the injured Lin Mo into a dark alley, two souls tricked by fate began a dangerous journey to the truth. On their way to escape, they accidentally met a pair of mysterious brothers and sisters - Lu Chen and Xiao Yu. These partners, who had been dependent on Lin Mo since the orphanage, have now grown into frightening "memory ghosts". Seeing Lin Mo's unfamiliar eyes, Lu Chen clenched his fists: "Morris, do you even want us to be erased from your mind?"
