Nude Fear is a 1998 Hong Kong psychological horror-thriller film directed by Alan Mak, starring Kathy Chow as a homicide detective pursuing a recently resurfaced serial killer who raped and killed her mother 23 years before.

While investigating a horrific rape-murder, she immediately recognises the killer's modus operandi — it's the same one used by the man who murdered her mother 23 years before.

The case is now closed, and the girl, having been identified as Cheung Sze-mei, reunites with her parents who lost her 12 years ago.

Officer Wong Wing-nin (Tse Kwan-ho) of the Public Relation Bureau arrives at Chan's apartment to celebrate.

While Wong is in the shower, Chan accidentally picks up his phone, and hears the voice of "Cheung Sze-mei".
