Limbo

A desperate investigation unfolds as Will Ren, a rookie fresh out of the police academy, teams up with his partner, veteran officer Cham Lau, to track down a serial killer targeting women. To lure this "hand-fetishist" murderer, they use Wong To-a convicted killer-as bait, forcing her to atone for causing an accident that shattered Cham's family. But Wong To is defiant and unpredictable. Fearing she may become the killer's next victim, she struggles to survive on her own in the slum where she is trapped.
