Broken City (2013)

In New York City, detective Billy Taggart goes to court for the murder of the suspected rapist Mikey Tavarez, but the Mayor Nicholas Hostetler and the Chief of Police Carl Fairbanks make the important evidence vanish and the case against Billy is dismissed by the judge; however, he is forced to leave the police department.

Seven years later, Billy is a private detective and lives with his girlfriend Natalie Barrow, who is an aspiring actress and the sister of Mikey's suspected victim. Billy's secretary Katy Bradshaw (Alona Tal) is trying to collect part of the debts to save their business. In the week of the elections, Hostetler summons Billy and offers $25, 000 to investigate his wife, Cathleen Hostetler, whom he believes is having a love affair. Billy discovers that Cathleen is meeting Paul Andrews, who is the coordinator of the campaign for Jack Valliant, the opponent of Hostetler and favorite in the election. When Paul is found dead on the street, Billy thinks that he has been double-crossed by Hostetler and he decides to investigate the truth behind Paul's murder.
