Sergeant Gerry Boyle (Brendan Gleeson, In Bruges) is a small-town cop with a confrontational personality, a subversive sense of humour, a dying mother, a fondness for prostitutes, and absolutely no interest whatsoever in the international cocaine-smuggling ring that has brought FBI agent Wendell Everett (Don Cheadle, the Ocean's trilogy) to his door. However, when his enthusiastic new partner disappears, his favourite hooker attempts to blackmail him and the drug-traffickers themselves try to buy him off, Sergeant Boyle finally realises that he needs to take matters into his own hands.
