Undercover cop Chan Chi-kit becomes a junkie in order to catch Mr Hung, the mastermind behind a crime syndicate.

Without having anything to do with S.P.L.’s first film (or Kill Zone), Hong Kong director Cheang Pou-soi gives his unique twist to the classic action scene. Beautiful cinematography by Kenny Tse helps bring to life each stunning set piece in this martial-arts drama, especially the prison riots.
