Xu Yuan, 28 years old, an investigative reporter for Jiangcheng Evening News, has been married to surgeon Zhou Yan for three years, and the marriage seems perfect. But she discovered that her husband would sleepwalk and disappear every night. He would leave bed at three o'clock in the morning and come back around five o'clock. She installed a hidden camera in her bedroom, and in the early hours of the fourth day, the footage showed Zhou Yan walking into the basement in pajamas - a room she had never been allowed to enter. The camera tracks deep into the basement, where another "Wish" is locked in an iron cage. She and she wore the same pajamas, had the same hairstyle, and even the mole behind her left ear was in the same position. When she looked up and smiled silently at the surveillance camera, Xu Yuan knew that this nightmare had just begun.
