The Big Swindle is a 2004 heist film written and directed by Choi Dong-hoon. It follows a group of four con men, one con woman, and one forger in a complex set of plots and counterplots against individual marks, against the Bank of Korea, against the police, and against each other.
Choi Chang-hyeok (Park Shin-yang) is driving in his car, when he suddenly finds himself followed by the police. In a nice car chase he tries to get away, but as his car emerges from a tunnel it goes over the side, down a cliff and he is killed in the burning wreck.
The reason he tried to get away, is that he had just left the Bank of Korea, where he was part of a scam, that got him and his four accomplices the neat sum of 5 billion won. He died, one of his accomplices was caught, and the other three disappeared – and so did all the money.
Eol-mae (Lee Moon-sik) was the one caught by the police, and they try to get him to talk and reveal the scam and his accomplices. In flashbacks we see how the plan was hatched, and get to know the criminals.
