In a top-secret movie about a sensational case which rocked Hong Kong in the 1970s, the two titans will face off against each other for the first time since their brief screen encounter in Bullet In The Head (1990).

Fans of TVB dramas will fondly remember their hit drama serial Police Cadet '85, in which Leung's hero cop battled Yam's thoroughly detestable and corrupt villain.
