SPL: Kill Zone

A witness is dead, and the crime lord Wong Po (Sammo Hung Kam-bo) is the reason, which leaves Detective Chan (Simon Yam) raising the man's daughter while he counts down to an early retirement. Inspector Ma (Donnie Yen), a martial arts expert, is already lined up to take over Chan's unit. Wilson Yip shoots the fights up close and fast, and the city around them stays dark and wet.
