The conclusion the film comes to is that the more we know, the less we can possibly hope to understand, with the moral centre of the picture,
good cop Jim Gordon (Gary Oldman), becoming complicit in a devil's bargain.
Starring James McAvoy, Jamie Bell, Eddie Marsan,
Jim Broadbent and Imogen Poots, the film follows
cop Bruce Robertson, a degenerate trying to solve a murder case and get a promotion, all while keeping the
good times rolling.
