Abducted by modern-day pirates and declared dead by his company, businessman Rokuro Okajima joins his captors on their ship, the Black Lagoon.

A gangster named Chin lures Dutch and the crew of the Black Lagoon into a battle at sea against Luak, the leader of rival pirates.

While on a mission to retrieve a valuable painting from a sunken U-boat, the Black Lagoon is besieged by missile-firing neo-Nazis.

After finding the painting on the sunken sub, Rock and Revy argue over looking for more loot while the neo-Nazis' own divers approach the wreck.

The Black Lagoon crew discovers too late that Roberta is a formidable opponent with a price on her head, as they attempt to flee with Garcia.

Rock learns the truth about Takenaka while under interrogation, and gets an even bigger surprise after he's rescued by Revy and Shenhua.

After Rock and Chang trace the twins' origins to Romania, they become engaged in a deadly game of cat-and-mouse with the lethal kids.

Yukio is abducted on the day she takes control of the Washimine Group, and Rock pleads with Ginji to let him and Revy help rescue her.

Rock tries to force Yukio out of a life of crime, but events beyond his control may cause his well-laid plans for her future to spin out of control.
