The Patchwork Man Swamp Thing scales the cliffs leading to the ancient castle of his late nemesis, Anton Arcane. Upon reaching its peak, he begins exploring Anton's laboratory, but a flagstone floor gives way beneath him, threatening to drop him into some unknown abyss. A zombie-like Patchwork Man is in the lab and tries to pull the Swamp Thing to safety. But he cannot keep his grip, and Swampy falls to the bottom of a vast cavern. The Patchwork Man then destroys the lab, causing the castle to explode.
In the nearby Balkan village, Interpol agent Matt Cable continues searching for the Swamp Thing. He blames him for the deaths of Alec and Linda Holland and wants revenge. He meets a medic at a nearby clinic named Abigail. Abigail just happens to be the niece of the mad scientist Anton Arcane. Matt and Abigail see the explosion of the castle and begin making their way towards the bridge that leads to the castle's cliffside.
The Patchwork Man appears, and Abigail faints from fright. He gingerly picks her up and begins taking her across the bridge. Swamp Thing appears (having climbed through the wreckage of the castle) and begins fighting the Patchwork Man. Abigail is about to fall from the bridge, but the Patchwork Man rescues her. Looking into his eyes, she realizes it is her father, Gregori Arcane – another sad experiment of her demented uncle.
Matt catches up with Abigail, and the two take a sea plane away from the Balkan village.
