In Beirut 1986, during the Lebanese civil war a Korean diplomat is taken hostage without a trace. Two years pass and long forgotten, a young diplomat Min-jun receives a phone call proving that the hostage is still alive. With the given mission, Min-jun is sent to Beirut to save the hostage with a bag of ransom money.

During the 1970s, in Kunchon, there were women divers who were able to dive without equipment, including two best friends Choon-ja and Jin-sook, Jin-sook's brother and Hammer. They always collected seafood under water for living. But, as fewer factories started to be built near the beach, the women divers started to have trouble with what they were doing for living. Without any choice, the ship crews decided to join the smuggling business in the water to seek a way for their living. But the smuggling business in their village got too big for Jin-sook's family to handle and the peaceful village was gradually broken.
