Casino Raiders is a 1989 Hong Kong action drama film written and directed by Jimmy Heung and Wong Jing and starring Andy Lau, Alan Tam, Idy Chan and Rosamund Kwan.

Crab Chan (Andy Lau) and Sam Law (Alan Tam) are a pair of renowned professional gamblers who are best friends.

One day, a tycoon named Lung (Charles Heung) summons the two of them to his casino in Lake Tahoe to crack a scam led by a pair of Japanese gamblers, Kung (Hagiwara Kenzo) and his son Taro (Lung Fong).

There, Crab and Sam also meet Koyan Tong (Idy Chan), a rich heiress from Hong Kong who is on vacation in the United States.

Taro wanted to gamble with Crab with a bet of HK$3 million, but the police unexpectedly break in.

In order to rescue Koyan, Crab is forced to pick between three glasses of wine, two of which contain poison.

The Americans also use this as a chance to compete with the Japanese for the interests of casinos in Asia, which created heavy gang warfare.

Taro does not want to cut off his arm and leg, so he shoots and kills his father and other audience members before being shot dead by both the Americans and Japanese.
