In Hong Kong, Ho Chen-tung is the aging Mob boss, living by a code of honor, keeping peace among rival factions. For years, he has been estranged from his son, Hui, who lives in Australia. Tung has become a sort of father to Han, a Vietnamese refugee who also lives by an ethical code. At the same time that Hui reaches out to his father, the Hong Kong CID conclude their years'-long effort to get the goods on Tung and his associates. Tung expects the younger gangsters to live by the code he loves, but at his trial, he has a surprise coming to him. It may be up to Han to restore the balance.

Yan Chi Yung (Chin Siu Ho) joins his fellow triad member Chu Chi Ang (Norman Tsui) in ripping off millions in gambling profits from their underworld boss Tai (Chen Kuan Tai), returning most of it after taking some for themselves. Meanwhile, a sexy gambler named Ice Chan (Ellen Chan), whose father was murdered by Tai several years before, arrives from America looking for revenge. She tries to infiltrate Tai's organization by seducing Yan, but really falls for him and fails in her attempt to assassinate Tai behind his back. More trickery and double-crosses follow as Tai tries to get Yan and Chu to help him rip off another gambler, only to have his plans thwarted by a turncoat within his own gang.
