A Senior Reporter named Richard Dees is contacted by his Director in order to write the story of a serial killer nicknamed "The Night Flier" for the Tabloid "Inside View". All the victims shows clear signs of vampirism due to wide injuries located on their necks. Dees initially believes that the murderer, a man who had named himself "Dwight Renfield", is only a lunatic who believes himself to be a vampire and begins to follow Dwight's trails. He's reclutantly teamed-up with Kathryn Blare, a newby he openly distrusts. Gathering further informations by interviewing all the witnesses he comes to know that Renfield travels during night between small Airports with a custom black Cessna 337G Skymaster marked "N101 BL". Some days after, while working together on Renfield's possible routes, the two are startled by a radio message stating that the Skymaster marked "N101 BL" has been located at the Airport of Wilmington. Not willing to loose the chance of his life, Dees fools Kathryn into believing he's going to share the scoop with her, but then he locks her into a closet and chases the killer alone. Flying on his airplane during a violent thunderstorm, he contacts the Airport via radio asking about the murderer's Skymaster and witnesses Dwight slaying all the people. He's then contacted by Renfield himself who advises him to turn back now that he still can do that. Dees' reply is a negative one. He finally manages to reach the Wilmington Airport before Renfield could flee and discovers the black Skymaster. After taking photographs of the infamous airplane, he decides to investigate further and finds out an old family album, possibly depicting Renfield's former lover. He then enters the Airport and is overwhelmed by the gory remains of Renfield's recent slaughtery. Feeling the urge to vomit, after falling badly into a large pool of blood, he reaches the Airport's bathroom and there he realizes he's not alone. Renfield enters the bathroom and proceeds to free his bladder of the unnecessary blood he fed on before. Then the vampire slowly walks towards Dees, crashing every mirror as he's coming near it. Dwight tells to Richard that he watched over him carefully and that he understands his true nature. Also Renfield notes that Richard's lust for blood is something that makes them almost brothers. Nonetheless Dwight's story is not meant to be told, as the Reporter should have clearly understood by now, and so he rips off every evidence that Richard collected minutes ago. Renfield reprises his speech and tells to the frightened man that he understands that Richard needs him, but others are in a similar need. Pulling Dees' hair backward the vampire tells Richard to relax himself because he's not going to die: he deeply respects Dees and believes that thanks to the obsessed Reporter, and the likes of him, the world is better and far more interesting for him. The monster states he'd satisfied his hunger for the night, but also threathens the man about devouring him if he continues to bother the vampire. Renfield walks away, but is followed by Dees who pretends to see the vampire' s face. Dwight stops for a moment, then tells Richard that he was expecting such a request because Dees had been looking for the vampire his whole life. Dwight walks towards the stubborn man and then, opening wide his mouth with a loud roar, allows Richard to witness his gruesome visage. Dees' mind is completely broken as the vampire appears near him and, opening a wound on his left wrist, forces the unwilling Richard to feed on the creature's cursed blood. Then Dees experiences hallucinations about being surrounded by Renfield's dead victims coming back to life as vampires in order to torture Richard, making him feeling guilty for parasyting and feasting on their deaths. Dees freaks out, grabs an emergency axe and begins to defend himself by chopping them badly. Two Policemen investigating the crime scene are shocked to see Richard, covered in blood from head to toe, who's proceeding to slice the corpses lying around to pieces. Richard, now completely out of his mind, sees Kathryn who had followed him to the Airport and rushes towards her, attempting to kill the young woman. The Police Officers shoots him dead and asks Kathryn who she is, she tells them her name and states that she's a Reporter for "Inside View". Meanwhile Renfield turns back to human and spits some blood out, clearly showing his sadness for causing Richard's death. After being advised to stay back by the Officers, Kathryn notices Renfield walking towards his airplane. Sensing she's staring at him, Dwight turns to her and seems to suggest something to the girl's mind. She agrees and witnesses the vampire leaving the Airport aboard the black Skymaster, then she joins the Policemen. The Officers questions her about the real identity of the dead man. She explains them that his name was Richard Dees, but he was best known as "The Night Flier". She then says to herself "I'm sorry Dees, you lost!" and takes a photo of her first scoop.
