Tony Leung Chiu-wai and Andy Lau Tak-wah return for the cathartic conclusion of the INFERNAL AFFAIRS trilogy, which layers on even more deep-cover intrigue while steering the series into increasingly complex psychological territory. Dancing back and forth in time to before and after the events of the original film, INFERNAL AFFAIRS III follows triad gangster turned corrupt cop Lau Kin-ming (Lau) as he goes to dangerous lengths to avoid detection, matches wits with a devious rival in the force (Leon Lai), and finds himself haunted by the fate of his former undercover nemesis (Leung). A swirl of flashbacks, memories, and hallucinations culminates in a dreamlike merging of identities that drives home the trilogy’s vision of a world in which traditional distinctions between good and evil have all but collapsed.
