Mad Detective

“I can see a person's inner personality.”

A colleague has gone missing, and Inspector Ho Ka-on (Andy On Chi-kit) brings in a man he should probably avoid: Chan Kwai Bun (Lau Ching-wan), a retired detective who is schizophrenic and claims he can see the hidden selves inside other people. Johnnie To and Wai Ka-fai send the two after a suspected policeman who may be living as several personalities. If Bun's mind gives out first, the one witness who can read the killer goes down with it.
