[EX Q]: In the Spanish countryside, a middle-aged man named HÃ©ctor (Karra Elejalde) and his wife (Candela FernÃ¡ndez) live in a home that they are renovating. HÃ©ctor scans the forest behind their house with binoculars and sees a young woman take off her t-shirt, exposing her breasts. When his wife goes shopping, he investigates and finds the woman on the ground, naked and unconscious. He is then stabbed in the arm by a mysterious man with pink bandages on his face. Fleeing and breaking into a mysterious nearby building, HÃ©ctor contacts a scientist (Nacho Vigalondo) by walkie-talkie, who warns him of the bandaged man and guides him to his location, promising safety. The scientist convinces HÃ©ctor to hide from the bandaged man, who is just outside, in a large mechanical device. However, when he leaves the machine, HÃ©ctor discovers that he has traveled approximately an hour back in time.The scientist explains that the machine is an experimental time travel device, and refers to HÃ©ctor as "HÃ©ctor 2". The scientist tells him that they need to stay where they are and let events unfold. Despite the scientist's warning, HÃ©ctor 2 drives off in a car, passing a cyclist, only to be run off the road by a van, cutting his head, which he wraps using the bandage from his arm wound. The bandage turns pink from absorbing the blood. The cyclist approaches to see if he is all right - it is the woman he earlier saw in the forest. He proceeds to replicate events by making her undress in view of HÃ©ctor 1. When she runs away, he catches her, inadvertently knocking her out. He lays her out naked on the ground and then stabs Hector 1 in the arm when he arrives. The woman escapes. HÃ©ctor 2 returns to his home, where he hears a scream and chases a woman through his house and onto the roof. When he attempts to grab her, she slips and falls to her death. Seeing the body from the roof, HÃ©ctor 2 is horrified, believing he has killed his own wife.HÃ©ctor then contacts the scientist over a walkie-talkie and convinces him to lure HÃ©ctor's past self to the lab with warnings that he is being pursued. Driving to the lab, HÃ©ctor 2 insists that he must travel back one more time, despite the scientist revealing that there is a HÃ©ctor 3, who told him he must stop HÃ©ctor 2 from doing just that.After removing his bandages, Hector 3 convinces the scientist to send him back several seconds before HÃ©ctor 2 appears. He finds a van and runs HÃ©ctor 2 off the road, but crashes as well, knocking himself out. Upon waking, he informs the scientist he has failed and to stop HÃ©ctor 2 by any means. He encounters the woman again, startling her into screaming, though she does not recognize him as her assailant. Since HÃ©ctor 2 has heard her scream, HÃ©ctor 3 and the woman flee to HÃ©ctor's house. They become separated. HÃ©ctor 3 finds and hides his wife, then realizes what has to happen / will happen / has already happened. He finds the woman, cuts her ponytail off, gives her his wife's coat, and tells her to hide upstairs. HÃ©ctor 2 chases her onto the roof.

Doctors are able to save her baby, but the woman dies of infection.Thirty-one years later, the child has become the vampire hunter Blade. He raids a rave club owned by the vampire Deacon Frost. Police take one of the vampires to the hospital, where he feeds on hematologist Karen Jenson and escapes. Blade takes Karen to a safe house where she is treated by his old friend Abraham Whistler. Whistler explains that he and Blade have been waging a secret war against vampires using weapons based on their elemental weaknesses, such as sunlight and silver. As Karen is now "marked" by the bite of a vampire, both he and Blade tell her to leave the city.Meanwhile, at a meeting of vampire elders, Frost, the leader of a faction of younger vampires, is rebuked for trying to incite war between vampires and humans. As Frost and his kind were not born as vampires and are therefore not pure-bloods, they are considered socially inferior. In response, Frost has one of the elders executed and strips the others of their authority.Upon returning to her apartment, Karen is attacked by a policeman, who is a "familiar", a human slave controlled by a vampire. Blade subdues the familiar and uses information from him to locate an archive of vampire history. Later, at the hideout, Blade injects himself with a special serum that prevents him from succumbing to his desire to drink blood, which would ultimately turn him into a vampire. However, the serum is beginning to lose its effectiveness due to overuse.While experimenting with the anticoagulant EDTA as a possible replacement, Karen discovers that it explodes when combined with vampire blood. She manages to synthesize a vaccine that can cure the infected, but learns that it will not work on a human-vampire hybrid like Blade. Frost and his men attack the hideout, infect Whistler, and abduct Karen. When Blade returns, he helps Whistler commit suicide and arms himself with special syringes filled with EDTA.When Blade attempts to rescue Karen from Frost's penthouse, he finds that his mother is one of Frost's followers. He is subdued and taken to the Temple of Eternal Night, where Frost plans to perform the summoning ritual for La Magra, the vampire blood god. Blade is drained of his blood, but Karen allows him to drink from her, triggering his vampirism. Frost completes the ritual and obtains the powers of La Magra. Blade kills all of Frost's minions, including his mother, and confronts him.
