Lock n' load with the baddest group of mercenaries ever to hit the high seas of Southeast Asia! Aboard their World War II torpedo boat, the Black Lagoon, Dutch the Boss, Benny the Mechanic, Revy Two Hand, and Rock, the salaryman from Japan, deliver anything, anywhere. In the dangerous underworld of the Russian Mafia, Chinese triads, Colombian drug cartels, crazed assassins, and ruthless mercenaries, it's hard to know who to trust. But if you've got a delivery to make, and you don't mind a little property damage along the way, you can count on the crew of the Black Lagoon!

The action shifts to chilly midwinter Tokyo, where Balalaika hires Rock as her interpreter, and Revy comes along as Rock's bodyguard. The Washimine-gumi, a Yakuza family on its way down, wants to make a deal with Hotel Moscow. Soon, however, the yakuza realize they might have been better off making a deal with the Devil himself! As the pressure builds, Rock faces the reality of his outlaw life, and Revy meets her match in the Washimine's number-one enforcer. The icy streets of Tokyo are about to burn red-hot!
