Award-winning actor Sean Lau Ching Wan goes undercover in the triads in the gritty cop thriller The Most Wanted. Blackie Lau (Sean Lau Ching Wan) was once a rookie cop who volunteered for undercover duty in the triads. After three years, Blackie is nearer to his goal of taking down a vicious armed robbery gang. But when the sting is botched and innocents die, Blackie is suspected of betraying the Royal Hong Kong Police Force, and is subsequently put on their "most wanted" list. Now wanted by the very people he serves, Blackie must prove innocence...but can he do it with both the triads and the cops after him?
