Rent Run and Kill (1993)

The world of happy-go-lucky family man, Cheung 'Fatty' Kau Ng (Kent Cheng), comes crashing down when he drunkenly orders a hit on his cheating wife, propelling him into the depths of a Hong Kong criminal underworld replete with bloodthirsty Vietnamese gangsters and an ex-military Mainland Chinese gang, whose members include the unstable Ching Fung, played with depraved glee by the legendary Simon Yam (Dr. Lamb, Fatal Termination). 'Run and Kill' is an unhinged cat-and-mouse thriller that takes nothing but nasty turns to a bitter end.
