Lin Xiao, after an accidental car accident, was sent to the famous "Tianan Nursing Home" to recuperate. The environment here is elegant, the doctors and nurses are friendly, the patients seem friendly, everything is normal... Except that there seems to be something wrong with her memory.
She discovered that some patients would suddenly disappear, and everyone claimed that they had never existed; the contents of the books she was once familiar with had been tampered with, and the "family" on the other end of the phone said she had dialed the wrong number; time became weird at certain moments, and the recurring number "0317" made her shudder.
Lin Xiao began to investigate and found that the sanatorium was hiding ulterior secrets - the patients here were not just patients, their memories had been modified, their identities had been erased, and their pasts were being rewritten! She decided to escape, but when she thought she had succeeded, she found that she was still in the nursing home...
Is she crazy, or is the world deceiving her? With the mysteries deepening and the truth approaching, can she break this "memory game" and find her true self?
