Out of the Dark

In a Hong Kong residential building, the security guards are haunted by evil spirits, and nobody seems able to stop it. Leon (Stephen Chow) goes looking for an exorcist and finds a stranger who is really an escaped mental patient, with Karen Mok Man-wai as Kwan. Jeffrey Lau stages every scare in the building's corridors, and Leon stands among them, flashlight shaking in his hand.
