Produced by Gordon Chan, shot four years ago and formerly known as Undercover vs. Undercover, Frankie Tam and Koon Nam Lui’s Undercover Punch and Gun revolves around Wu (Philip Ng), an undercover cop who’s grown much too attached to Bob (Lam Suet), the mob boss he was supposed to help bring down, to the extent that he’s now dating his daughter (Aka Chio). When Bob is killed during a drug deal gone wrong, Wu finds himself caught between his superior officer (Nicholas Tse) who wants him to go deeper, Bob’s ruthless collaborator and old flame (Carrie Ng) who is suspicious towards him, and Ha (Andy On), a former special agent gone bad, who operates a meth trade from a cargo ship on the high seas, and wants the beleaguered undercover to deliver Bob’s chemist (Susan Shaw) to him. A desperate Wu can only count on the help of his loyal informant (Vanness Wu) and a special agent (Joyce Feng) who used to work with Ha.
