Michael Logan is a police detective in London. His area is drugs and this brings him into contact with European drug syndicates. Logan is happy to turn a blind eye to their dealings, for a cut, or confiscate suppliers' merchandise for their own profit. So far he and his equally-crooked police colleagues have done quite well out of this. Then a deal he was planning with a member of a Turkish drug cartel goes sour and the balance of power swings to an Albanian gang, run by two brothers, the Kabashis. Logan quickly aims to provide the Albanians with the same service he provided the Turks, but they aren't easily lead. Meanwhile, he an his colleagues are being investigated by Internal Affairs. Just to make his life more complicated, he has been seconded to a vice task force, run by a former colleague whom he does not get along with.
Gritty crime-drama that blurs the lines between good and bad, criminal and cop. Very well done in this respect, as you never know who is on whose side, who's looking out for justice and who's just it for the money. Even figuring out who are allies on the criminal side of things is difficult.
All this leads to a wonderfully complex minefield or relationships, loyalties and intentions, and in the middle of it is our main character, Logan.
Just a pity about the ending though. The movie was heading for great climax, and maybe even a 9/10, when the director wrecked it with the final scene. Without giving too much away, it was very unsatisfying...
