Insanity

Insanity begins with an introduction to disturbed schizophrenic Fan Kwok-Sang (Lau Ching-Wan), but the film is really about his doctor, Chow Ming-Kit (Huang Xiaoming). Three years ago, Sang was committed to a psychiatric hospital after his paranoia and violent temper led to the accidental death of his wife Wai-Ling (Michelle Ye). Now he’s up for release and Doctor Chow proudly vouches for him against the objections of his senior, Doctor Lui (Alex Fong). Soon, the increasingly arrogant Chow finds his career on an upward trajectory, with the cherry-on-top being his appointment as director of the hospital by the former head, terminally ill Doctor Lau (Mo Chun-Fai). Meanwhile, Sang isn’t doing quite so well; his mother-in-law (Bau Hei-Jing) harasses him by pretending to care about him while also promising to haunt him for the rest of her days. Then something very bad goes down with Sang, and Kit becomes obsessed with defending his patient – not to mention his own reputation.
