The Regional Crime Unit officer Chan Kwok-ming and his wife Sammi Mok are on their way to finalize their separation when an armed robbery erupts in the streets. Kwok-ming steps in to help pursue the fleeing criminals and protect Sammi amid the chaos. The scene shifts from a personal divorce matter to a dangerous street confrontation.

Sammi is hit by a stray bullet during the robbery and falls into a coma. Kwok-ming and medical teams rush to her side, but her life hangs in the balance. The event marks the couple's immediate crisis as their separation is interrupted by violence.

Several months pass and Sammi awakens from her coma, beginning a fragile recovery. Her doctors warn that her blood type is very rare and that she must be extra careful with her health. The warning foreshadows the later connection to medical needs tied to her blood type.

Sammi's doctor emphasizes that her rare blood type could complicate any transfusions or treatments. The revelation heightens the stakes for her recovery and for Kwok-ming's ability to support her from afar. The warning plants the thematic link between her condition and future events.

Kwok-ming remains busy at the police station, leaving Sammi to recover at home. She begins experiencing vivid hallucinations as loneliness and stress take their toll. The line between reality and dreams becomes increasingly blurred.

In a troubling hallucination, Sammi sees Kitty Chow, a female celebrity, killed before her eyes. The vision unsettles her and hints at a danger connected to Kitty's murder. She remains skeptical but the episode unsettles her sense of reality.

Driven by a mix of fear and curiosity, Sammi walks into the back alley of a bar and discovers Kitty Chow's corpse. The discovery confirms part of her hallucination and tugs the investigation toward the celebrity’s death. The shock deepens her mental crisis and ties the case to the real world.

Kwok-ming's supervisor orders him to cancel all leaves and focus on investigating Kitty Chow's murder. The demand pressures him as his personal life and Sammi's condition hang in the balance. He resolves to push forward despite the mounting strain.

One night, Kwok-ming returns home to find the walls covered in messages written with blood. The macabre signs heighten the sense that the case and Sammi's deteriorating condition are connected to something supernatural or staged. The eerie scene intensifies the mystery surrounding Kitty Chow’s murder.

Sammi goes mad and heads into the road, causing serious traffic congestion. She is later taken to a hospital for examination by a psychiatrist. The incident marks a turning point as both her health and the Kitty Chow case intensify.

Kwok-ming investigates another linked case—the murder of a lawyer connected to Kitty Chow. At the crime scene, the lawyer suddenly comes back to life, shocking everyone. He is then taken to the hospital for treatment.

In the hospital, doctors reveal that the revived lawyer requires an emergency blood transfusion from a rare blood type, which happens to be the same as Sammi's. This startling blood tie deepens the stakes of the investigation. Just as the link becomes clear, Sammi mysteriously goes missing, leaving the story with a chilling cliffhanger.
