The storyline follows a-team of pirate mercenaries called Lagoon Company, that smuggles goods around the seas of Southeast Asia in the early to mid 90's. Their base of operations is situated in the fictional seaport city of Roanapur in south-east Thailand (someplace in the Amphoe Mueang Trat district, probably on the mainland north/north-east of the Ko Chang island or on the isle itself). The isle is home to an extensive range of all kinds of pickpockets, thugs, mercenaries, thieves, prostitutes, assassins, and Gunmen, the Triad, French and Cuban cartels, and the Yakuza. They transport items in the 80-foot (24 m) Elco-kind PT boat Black Lagoon. Lagoon Company does business with various customers, but has a specially friendly relationship with all the Russian crime syndicate Hotel Moscow. The group assumes many different assignments--which might involve brutal firefights, hand-to-hand combat, and nautical conflicts--in different Southeast Asian places, even going as significantly as Phu Quoc island of Vietnam and when not doing much, the members of the Lagoon Company spend much of the down time in The Yellow Flag, a pub in Roanapur which is usually ruined in firefights.
