The story follows a team of pirates/mercenaries known as Lagoon Company, that smuggles goods in and around the seas of Southeast Asia in the early 1990s. Their base of operations is located in the fictional city of Roanapur in Thailand, and they transport goods in the 80-foot (24 m) Elco-type PT boat Black Lagoon. When on land, they move around and conduct business using Benny's 1968 Plymouth Road Runner, although in episode 24 he's seen driving a 1965 Pontiac GTO after his Roadrunner is blown up in episode 17. Lagoon Company does business with various clients, but has a particularly friendly relationship with the Russian crime syndicate Hotel Moscow. The team takes on a variety of missions—which may involve violent firefights, hand-to-hand combat, and nautical battles—in various Southeast Asian locations and when not doing much, the members of the Lagoon Company spend much of their downtime at The Yellow Flag, a bar in Roanapur which is often destroyed in firefights.
