Countryside detective Byung-su (KWAK Do-won) goes on a family holiday to the Philippines to celebrate his tenth wedding anniversary to his wife. However, there’s more than meets the eye with this trip, as he’s also looking to track down his old friend Yong-bae (KIM Sang-ho), who scammed him out of a lot of money and escaped from him several years ago scot-free. Of all places, Byung-su finds Yong-bae in a prison in Manila, where he is serving a sentence for murder. The convict then fills him in on a local murder case surrounding ‘Yamashita’s Gold’ and after being tempted by a share of the gold at the heart of the affair, which Yong-bae offers to him, he decides to involve himself in the case.
