SPL 2: A Time for Consequences

Chan Chi-Kit (Wu Jing) is an undercover officer who wants to bring down a syndicate from the inside, and instead he ends up a prisoner of the people he was sent to watch. Chatchai (Tony Jaa), the guard assigned to keep him, slowly becomes the one person Kit can talk to, and together they uncover an organ trafficking ring. Soi Cheang puts both men in the syndicate's reach, where Kit's cover and Chatchai's loyalty are the only things keeping either alive.
