3 (The X-Files) - Plot

Plot

In Los Angeles, Garrett Lorre, a middle-aged businessman, embarks on a one night stand with an anonymous woman he has met at a corporate party. However, as they are having sexual intercourse in his hot tub, the woman bites Lorre to drink his blood. Two other men join the woman, helping her rape Lorre by repeatedly stabbing him using hypodermic needles as a form of sexual assault.

The following day, before departing for Los Angeles, Fox Mulder stores the missing Dana Scully's FBI badge in an X-File and files it under her name. At the crime scene, Mulder meets with the LAPD detectives investigating the case, explaining that Lorre's murder is the latest in a series of seemingly vampiric serial killings that have spanned two other states. Because the killers write biblical passages in the victims' blood, Mulder believes that they view themselves as an "Unholy Trinity".

Mulder visits a local blood bank where a night watchman has been recently hired. Mulder has him arrested after he is caught drinking blood in the facility's storeroom. During his interrogation, the suspect tells Mulder that he belongs to a trio of vampires who desire immortality; he is known as "The Son" while the other two, a man and a woman, are called "The Father" and "The Unholy Spirit". Mulder does not believe The Son's claims. However, at sunrise, The Son is burned to death when sunlight from the window touches his flesh. Mulder is taken aback, having previously assumed vampires to be purely mythological.

During an examination of The Son's body, Mulder discovers a tattoo for Club Tepes, a local vampire club. There, he comes across a young woman named Kristen Kilar who partakes in the consumption of blood. Mulder, having his suspicion aroused, follows Kristen after she and another club patron, David Yung, leave for an erotic liaison; he initially fears that Kristen is targeting Yung, but is beaten by Yung when he catches the agent spying on them. After Mulder leaves, Yung is murdered by the three killers.

Mulder runs a background check into Kristen, discovering that she formerly lived in Memphis and Portland—both the previous locations of earlier murders. Mulder assists the LAPD in searching Kristen's home, where he finds various blood-related paraphernalia. When Kristen arrives later, Mulder is waiting for her. Kristen tells Mulder that she met The Son, then known as John, in Chicago and that they had drunk each other's blood. Later Kristen fled John as he got together with the Unholy Trinity, but they followed her across the country. Mulder and Kristen kiss while The Son, alive after all, watches on.

The next morning The Son confronts Kristen and tells her that by killing Mulder and drinking the blood of a believer, she will become one of them. Kristen approaches Mulder with a knife but instead stabs The Father, who is hiding in the bedroom. The Son attacks Mulder but Mulder overcomes him and ties him up. Mulder and Kristen try to escape with the car but are attacked in the garage by The Unholy Spirit. Kristen drives into her, impaling her on a wooden peg on the wall. Kristen tricks Mulder into running outside of the house while she goes back inside and pours gasoline all over the house. Kristen lights a match, blowing up the house and taking her own life in order to kill the other vampires. Firefighters find four bodies in the wreckage while Mulder stares at Scully's cross necklace.
