Detective Inspector Gerry Boyle (Brendan Gleeson), County Galway, Dublin, Ireland () cleans up the mess caused by the drug addict's sudden death in a car accident, and welcomes the newly arrived detective McBride. They investigate the crime scene and deduce the type of killer from the evidence. Unfortunately, the two have very different ideas. Boyle's thinking was so bizarre that McBride completely lost the point. They once interrogated the suspect together, but found that he was just a scapegoat and the real murderer was still at large. Although Boyle is cynical, he is a filial son. When his mother's death is approaching, he goes out of his way to make her happy. In order to crack a drug smuggling case with a black market value of 500 million, US FBI agent Wendell (Don Cheadle) began to analyze the case for the police officers, but was repeatedly interrupted by Boyle. Just when his boss was about to fire Boyle, the latter pointedly pointed out the biggest flaw in the report - one of the four suspects was already lying in the morgue. This made Wendell look at Boyle who made jokes about racial discrimination with admiration. McBride was accidentally killed by a philosophical gangster while on duty. His wife came to look for her husband, which made Boyle feel a heavy responsibility. He and Wendell embarked on a journey to find the murderer...
