Blade warrior Brad's mother was bitten by a vampire when she was pregnant and died after giving birth to him. As a result, Brad (Wesley Snipes) took half of the blood of a vampire. Brad grew up in the family of weapons expert Abraham. Abraham (Kris Kristofferson) made the most powerful weapons against vampires for him and injected him with drugs to prevent him from becoming a vampire. Brad has always been the protector of mankind and the nemesis of vampires. When he repeatedly destroyed the good deeds of vampires and hunted countless vampires, the vampire king Foster (Stephen Dorff) vowed to get rid of this big worry. He first persuaded Brad to join their ranks, so that they would be invincible. Then he designed to get Brad's blood, because in this way he could use his blood to perform blood sacrifices and call up a blood tide, so that all people would become vampires. Can Brad finally defeat this powerful enemy?
