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 harbor city of Roanapur in the south-east Thailand (somewhere in the Amphoe Mueang Trat district, likely on the mainland north/north-east of the Ko Chang island or on the island itself). 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, even going as far as Phu Quoc island of Vietnam and when not doing much, the members of the Lagoon Company spend much of their down time at The Yellow Flag, a bar in Roanapur which is often destroyed in firefights.
This is an "old" anime that has the general art style of the "old" times, its hard to explain exactly what the "old" style of animating is but if you watch some newer animes, High School of the Dead, you can tell the art style is more "new". The first two seasons are done in the old style while the OVA is done in the newer style, either way, its pretty graphically violent in all three seasons. The entire idea of the anime is basically hot women wielding guns, not too much of a plot there. The main character Rock is your typical "out of place" guy that represents us in a sense. Its pretty entertaining and it has some interesting moral decisions that the characters go through that are pretty insightful.
