Shenzhen, one stormy evening. Data engineer Su Man personally puts her ex-boyfriend Zhang Peng at the center of a police investigation. In the living room of his ex-wife, Zhou Yawen, a hard drive engraved with Zhang Peng’s name becomes irrefutable evidence in a major illegal-surveillance case. Zhou Yawen’s hysterical accusations, the shattered trust in Zhang Peng’s eyes, and the fact that the hard drive’s password is linked to Zhang Peng’s private phone number... Every clue is bound together in a bizarre tangle. The old promise, “Come marry me once you’re divorced,” has grown cold and distant in the whirlpool of evidence and betrayal. Su Man is torn between her professional duty and feelings that have yet to fade, while the storm’s center is quietly shifting toward the seemingly innocent Zhou Yawen. As fragments of the truth cut through the mask of lies, love, hatred, and conspiracy beneath Shenzhen’s neon lights are dragging everyone into deeper darkness.
