Plot
A small group of vampires, led by the Talos siblings, Danica and Asher, and their bodyguard Jarko, investigate an ancient tomb in the Syrian Desert, which they believe belongs to the first vampire Dracula, also called "Drake". To keep Blade from interfering, they frame him for the murder of a human familiar. FBI agents subsequently locate Blade's hideout and kill his mentor and friend, Abraham Whistler. Demoralized, Blade surrenders and is arrested. The vampires' familiars have arranged for the authorities to turn Blade over to them. He is rescued by Hannibal King and Abigail Whistler, Abraham's daughter, who invite Blade to join their band of vampire hunters, the Nightstalkers. From them, Blade learns that the vampires have revived Drake, intending to use his powers to cure vampires of their weaknesses. As the first of the vampires, Drake can survive in sunlight. Along with newly innovative ultraviolet "sundog" ammunition, the Nightstalkers' blind scientist, Sommerfield, has created an experimental viral bioweapon known as Daystar, capable of killing vampires at the genetic level.
However, to make it effective, they need a pure blood source. Drake is too powerful to kill because he is immune to any vampire weaknesses, including sunlight, so they hope that the virus will kill him and, with his blood in the mix, ensure the rest of the species is wiped out. Eager to test Blade, Drake isolates him from the Nightstalkers. He explains his view that all humans and vampires are inferior in his eyes and that he intends to wipe them out. Abigail finds evidence of the vampires' plans for human subjugation, a network of "blood farms" where brain dead humans are drained of their blood for vampire consumption. Blade deactivates the farm's life support systems and executes the familiar cop who had been rounding up humans for the vampires. Returning to the Nightstalkers' hideout, Abigail and Blade find all of them dead except for King and Zoe, Sommerfield's daughter, both of whom have been taken captive. A recording left by Sommerfield reveals that Drake's blood is all that is needed to make it effective, but she also warns that Blade might be killed, too. King is tortured by the vampires for information, but refuses to talk, even when they threaten to turn him, starve him, and then give him Zoe to feed on.
Blade and Abigail arrive and free the captives. Abigail kills Asher while King kills Jarko. Blade and Drake engage in combat until Drake bests him. As Drake prepares to kill Blade, Abigail fires the Daystar arrow, but Drake catches the arrow before it drops. This distraction allows Blade to stab Drake with the Daystar arrow, triggering a chemical reaction that completes the virus and releases it into the air, killing Danica and all the vampires. As Drake slowly succumbs to his wounds and the virus, he praises Blade for fighting honorably but warns him that he will eventually succumb to his need for blood, acknowledging that Blade is the vampire race's future. Using the last of his power, Drake shape-shifts into Blade, allowing the latter to escape. The FBI recovers the body, but as they begin the autopsy, it transforms back into the deceased Drake.
