Mild-mannered Rokuro’s business trip to South East Asia takes an unexpected turn when he’s taken hostage by modern-day pirates Revy, Dutch, and Benny.

The Black Lagoon is pinned down by an attack chopper, and Rock devises a risky plan to turn the tables. When it’s all said and done, the disk is delivered - and the Black Lagoon gains a new crew member.

A gangster isn’t pleased with Dutch’s decision to throw in with Balalaika. Later, the Black Lagoon is attacked by a small nay of attack boats, and it might be a set-up.

The crew is out to retrieve a painting from the wreckage of a sunken Nazi U-boat. As Revy and Rock take to the depths to claim their prize, the Black Lagoon falls under missile attack on the water’s surface.

Just as it seems that the painting is secure, Revy and Rock fall under attack in the sunken U-boat. The Nazis unload with everything they’ve got - but Dutch is already formulating a plan.
