By chance, Evan (Christian Bale) meets the sexy and beautiful stripper Sidney (Amy Adams). The two people, who have similar interests, fall in love at first sight and soon fall in love. Unexpectedly, Evan was a professional liar. Under his encouragement and the influence of "the power of love", Sydney resolutely joined in, and the two worked together to run the "career" in a lively and colorful manner. However, how can you not get your shoes wet when walking along the river? The police have long targeted Evan and Sidney, who have a rather high-profile behavior style, and finally arrested the two in a carefully planned operation. Unable to resist the lobbying and temptation of FBI agent Rich (Bradley Cooper), Evan and Sidney decide to cooperate with him to "atone for their sins." Although they had picked up their old profession, this time Evan and Sidney were clearly on the side of justice because their opponents were corrupt officials who took bribes and bent the law.
