The film "american hustle" is adapted from the corruption case of the US Congress in 1980s. What is the true story of this case?

American hustle was adapted from a real case of the FBI in the late 1970s and early 1980s: Operation fishing law enforcement, code-named ABSCAM. ABSCAM is the abbreviation of "Arab-scam" (corresponding to "Arab Sheikh" as bait). This is a film with strong American elements-of course, it doesn't refer to those movie elements that Hollywood sells all over the world: action, explosion, science fiction, big scenes (there is none in this film), and it doesn't just refer to the "American wash, cut and blow" shapes, urban landscapes, BGM, and social and economic background of that particular era in the movies of the 1970s and 1980s. Although this is a criminal story of fraud, fishing law enforcement and officials taking bribes in a specific era, no words will simply tell its superficial story.
