Suen is a depressed and rundown cop still obsessing over his girlfriend’s sudden disappearance 10 years ago. While Suen extradites a witness, his bounty is murdered by an oddly principled assassin who seems to possess information that Suen himself would kill for. The witness’ death is welcome news for a crooked businessman whose assets were frozen by the police, until his only son is kidnapped. Enter To, a lawyer who has always successfully protected his clients, and who coincidentally happens to be married to a woman who looks exactly like Suen’s missing girlfriend. Each of these men will ultimately and painfully be drawn together until a violent and permanent Divergence becomes this film’s only forgone conclusion.
