Taxi driver Tae-gyun receives a call from his younger brother Tae-min. He asks Tae-gyun for help, saying that his car "Thunderbird" was pawned and in it, there is a lot of money that he won from gambling. Now Tae-gyun, who urgently needs money, Tae-min, a gambling addict sitting in a pile of debt, and Mi-young, Tae-min's girlfriend who is a former casino dealer, all go out to get the car back.
