American Hustle (2013)

Plot: 1978. When Irving Rosenfeld and Sydney Prosser meet, there is an instant emotional connection since they can see themselves in the other, in what each wants in life. Both come from humble backgrounds, but are striving for a better life. They embark on a sexual relationship, despite Irving already being married to the brash and uncultured Rosalyn Rosenfeld; most likely he does not divorce her due to his affection for her son, Danny Rosenfeld (whom he has adopted), whom he would not want left alone with his largely unfit mother. Irving tells Sydney about his illegal sideline as a con artist, but to his surprise she is not repulsed but rather attracted to the fact (besides his legitimate businesses, he deals in loan scams which net him $5,000 each). Sydney believes she can help his scams by pretending to be British Lady Edith Greensley who has London banking connections. In doing so, she does indeed vastly improve the scams and their take. However, one of their targets ends up being Richie DiMaso, a low level FBI agent trying to make his mark in the agency. Richie knows that Sydney is not a Lady nor does she have London banking connections but he does believe she is a Brit named Edith Greensley. Richie makes a deal with them to help him nab four additional white collar criminals in exchange for their release without charges. Ultimately, Richie talks them into bigger fish than was originally intended: nabbing politicians and mobsters as the opportunity arises. Their initial target is a Camden, New Jersey Mayor called Carmine Polito, who is trying to revitalize Atlantic City as a gambling mecca, which requires an influx of investments in the millions. But in getting these offshore investments (which in reality don't exist), the bigger fish include congressmen and senators, who may be taking bribes in this revitalization, as well as a mobster named Victor Tellegio, the right hand man of Meyer Lansky. Beyond their marks' finding out what they're doing -which could be especially deadly in Tellegio's case- their collective problems include: Stoddard Thorsen, Richie's immediate supervisor, who repeatedly refuses Richie's expensive requests for the wherewithal to complete the sting convincingly; Rosalyn, whose own self-interest is her primary focus, even at the possible risk of Irving's life; and Sydney's relationship with Richie, whom she initially seduces to keep him close "just in case", but with whom she may really be falling in love.
