"异域深眠" translates to "Deep Sleep in a Foreign Land". So, the phrase can be translated as: "The Love and Hate Entanglement Behind the Dismemberment Case in 'Deep Sleep in a Foreign Land'"

Private detective Xu Chuan, who is unknown to the public, received a bizarre missing person's case. Unexpectedly, overnight, the client was found dead in a mysterious way downstairs from Xu Chuan’s office building. The condition of the body was exactly the same as that of a recent dismemberment murder victim. Moreover, the person Zhang Xuan, who Xu Chuan was asked to find, was pointed out by Wu Tao as Xu Chuan’s ex-girlfriend. However, other than her name, Xu Chuan has no memory of this "ex-girlfriend".

Xu Chuan assisted Wu Tao in the investigation. As the case progressed and more information came to light, it became increasingly strange. Xu Chuan discovered that the serial dismemberment murders were closely related to him, and he himself was even suspected by the police to be the murderer. In order to clear his name, Xu Chuan and policewoman Xu Jia pursued the investigation further. A long dormant dismemberment murder case resurfaced, and the face behind the series of dismemberment murders gradually emerged.

Cornered by overwhelming evidence, the murderer committed suicide, but it was far from over...

The truth, is far from being revealed. The killing intent, is imminent.

A battle of wits, a clash of intellects, a collision of human nature,

Until the last second, you will never know the truth.
