Roy (Nicolas Cage) is a professional liar with superb means. He has a bold and greedy partner Frank (Sam Rockwell). They have been partners for many years and have hardly missed. At the same time, Roy is also a patient with obsessive-compulsive disorder. He loves cleanliness and does not allow others to walk into his house with shoes; he is cautious and checks the gas and power switches repeatedly every time he goes out. Frank helped him find a psychologist for this. With the help of the psychologist, Roy found his long-lost daughter Angela (Alison Lohman). The appearance of his daughter changed his life and made him slowly feel the joy of being a father. But he didn't want his daughter to know his profession. But after all, the paper can't cover the fire. The daughter knew his secret and showed an extremely outstanding talent for deception. Roy decided to pass all his skills to his daughter. Soon, a "big deal" came, and the father, daughter, and partners went into battle together. What will be the result?
