American Hustle is written and directed by David O. Russell (Silver Linings Playbook, Three Kings) and he carries on his theme here of trying to present "human opera".
It is a work of fiction although some of the characters are based upon real-life counterparts from the criminal world.

Irving is worried that although he loves Sydney, if he leaves his wife, Rosalyn (Jennifer Lawrence - Silver Linings Playbook, The Hunger Games) she will deny him access to her son Danny. She has also threatened to go to the police with details of his work if he tries to leave.
Things begin to go downhill with the introduction of FBI Agent Richard "Richie" DiMaso (Bradley Cooper - The Hangover Part III, Limitless), who is about as corrupt as they come.
