A half-vampire, half-human hybrid known as the Daywalker walks the night as a feared vampire hunter, utilizing his unique strengths to track down and eliminate the bloodthirsty undead that prey on humans. Haunted by his mother's death during his birth—bit by a vampire as she was in labor—the Daywalker, armed with a specialized arsenal and assisted by his mentor and weaponsmith, dedicates his life to a war against vampires, intent on avenging his mother's death and protecting humanity from the vampire scourge. With his immunity to vampire bites and the ability to withstand sunlight, he tirelessly patrols the urban shadows, a solitary guardian against the darkness.

An ambitious and ruthless vampire overlord seeks an ancient ritual that would grant him and his kind the ability to walk in daylight, effectively eliminating their few weaknesses and allowing vampires to rule the earth unopposed. Targeting a specially-bred human woman carrying the rare blood type needed for the ritual, the overlord aims to harness her blood and invoke a prophecy that would change the balance of power between humans and vampires forever. As the Daywalker learns of these sinister plans, he finds himself in a race against time to thwart the overlord's scheme, navigating through a world where loyalties shift as quickly as shadows, and every victory is etched in blood and darkness.
