Z Storm director David Lam & leading man Louis Koo return for the sequel S Storm, an exciting crime thriller again centered around the workings of the ICAC, Hong Kongs corruption watchdog law enforcement agency. Corruption within another quintessential Hong Kong institution, the citys official horse racing & betting operator Jockey Club, sets off a long & sinister trail of crime, conspiracy & collusion that runs far deeper than meets the eye. Adding to the local appeal is a cast filled with former TVB stars including Julian Cheung, Bowie Lam, Ada Choi & Shek Sau, as well as Lo Hoi Pang, Dada Chen & Taiwan actor Vic Chou.
ICAC agent Luk (Louis Koo) is investigating the case of a Jockey Club trader suspected of accepting bribes & fixing sports betting odds. The suspect, however, gets murdered in broad daylight by a hitman (Vic Chou), & Luk is the only witness. Detective Lau (Julian Cheung) is put in charge of the murder case, but in a classic example of ICAC & police deadlock, he is unable to get much information out of Luk. The two agencies delve into the victims connection with illegal bookmaking operations & discover that there is a mysterious & ruthless big boss pulling the strings.
