Black Lagoon(2002)

BLACK LAGOON

Rokurō Okajima is just an average Japanese salaryman, living an average life. But when he's taken hostage by the crew of the Black Lagoon, Rokurō finds himself thrown headfirst into a deadly world of outlawed heroes, brutal villains, and blazing gunfights. Where he ends up is anyone's guess, but one thing is for certain—he's in for a wild ride!
