The plot revolves around the Lagoon Company, a group of pirate mercenaries who smuggle goods in and around the seas of Southeast Asia in the early to mid 1990s.[4] Their base of operations is in the fictional harbor city of Roanapur in east Thailand near the border of Cambodia (somewhere in the Amphoe Mueang Trat district, likely on the mainland north/northeast of the Ko Chang island or on the island itself). The city also has a big Vietnamese refugee population as a result of the Vietnamese refugee flight following Vietnam's Communist takeover.
