Blade is a film and television franchise based on the Marvel Comics character of the same name.
The Daywalker known as "Blade" - a half-vampire, half-mortal man - becomes the protector of humanity against an underground army of vampires.
A rare mutation has occurred within the vampire community - The Reaper. A vampire so consumed with an insatiable bloodlust that they prey on vampires as well as humans, transforming victims who are unlucky enough to survive into Reapers themselves. Blade is asked by the Vampire Nation for his help in preventing a nightmare plague that would wipe out both humans and vampires.
Vampires investigate an ancient tomb in the Syrian Desert, which they believe belongs to Dracula, the first vampire. To keep Blade from interfering, they frame him for the murder of a human Familiar spirit. Federal Bureau of Investigation agents subsequently locate Blade's hideout and kill his mentor and friend, Abraham Whistler. Demoralized, Blade surrenders and is arrested.
On the mean streets of Detroit, an ancient evil is growing bolder by the day. The House of Chthon is on the verge of eliminating the final barriers to their supremacy over mankind, and only the Daywalker can stop them. Half human, half immortal. His only allies are a master weaponsmith and a woman obsessed with revenge against Chthon. And he will stop at nothing to win his war, because he is the ultimate vampire hunter. His name is Blade.
