In fact, his hidden agenda is to track down his old friend Yong-bae who scammed him and got away a few years ago. In Manila, Byung-su finds Yong-bae in prison for murder, and hears about the case surrounding ‘Yamashita’s Gold’. Swayed by a share of the Gold that Yong-bae offers, Byung-su suddenly becomes embroiled in the case.
