The storyline follows the main events of the original Black Lagoon series, featuring the thriving underworld of Roanapur, Thailand. Here, in this lawless city that’s home to criminals and mercenaries, the Lagoon Company – a team of pirates – operates as couriers. The team comprises the Japanese salaryman Rokuro "Rock" Okajima, who has turned his back on his former ‘respectable’ life, the volatile, gun-slinging Revy, the amicable Bear and the witty hacker, Dutch. Grappling with their moral compasses while sweating it out in the rough terrains and murky waters of the Southeast Asian seas, the Lagoon Company undertakes high-risk jobs while facing numerous perils.

Roberta's Blood Trail primarily focuses on Roberta, the enigmatic, lethal former FARC guerrilla turned maid who was previously featured in the Black Lagoon series. Famous among the Roanapur underworld as "Bloodhound," a person who has a blood-soaked record of destruction, Roberta is a force to be reckoned with. After the death of her master - whom she served with unwavering loyalty, she embarks on a relentless hunt for the truth, setting her on a path of bloody vengeance.

While the city of Roanapur is no stranger to violence, the arrival of the bloodthirsty Roberta puts the denizens of the city on the edge. Everyone from crime syndicate leaders to street-level thugs must confront the wrath of the seemingly unstoppable maid.

Amidst this chaos, the young master of the Lovelace family, Garcia, is desperate to save Roberta from her frenzied quest for vengeance and her inevitable self-destruction. To do this, he hires the Lagoon Company to track her down - setting Rock, Revy, and the rest of the Lagoon crew on a dangerous mission against Roberta. However, catching Roberta, who has been pushed beyond the brink of sanity, is easier said than done.

The OVA brings back the darkness and grit, characteristic of the original Black Lagoon series while further delving into the personal histories, motivations, and emotional struggles of its characters.
