An ex-cop finds himself in over his head when he agrees to help out the mayor of New York City in this tense political thriller from director Allen Hughes. Having had to sacrifice a promising career when he was involved in a controversial shooting, tough street cop Billy Taggart (Mark Wahlberg) is spared a prison stretch by the intervention of the city's popular Mayor Nicholas Hostetler (Russell Crowe). Starting afresh as a private investigator, Billy is soon hired by Hostetler to find out if his wife (Catherine Zeta-Jones) is being unfaithful. But when her suspected lover is later found dead, Billy realises too late that the mayor's motives run deeper than expected, and that if he's to stay alive, he needs to take the fight to his opponents, risking all to reveal the truth.
