Chun Dalsoo, a scoundrel who has nothing better to do, makes his living by attending military exercises in place of his friends. One day, he goes to the bank with Eunji, a cashier in a cafe who wanted to ask the bank for delayed payments. To Dalsoo's surprise, he finds ten billion won in his bank account. It is the ex-president's secret money hidden in Dalsoo's bank account, a randomly selected account that has not been in use for years. When Dalsoo withdraws 300 million won, a secret organization hires a professional killer named Jang to follow Dalsoo and Eunji. Everybody seems to be chasing somebody else: Dalsoo and Eunji who suddenly possesses 10 billion won, Hang and the members of his organization who are chasing Dalsoo and Eunji, and prosecutor Park who is investigating the corruption.
