Myra and her friend Nola deliberately switch a chemical to burn Nancy during chemistry class, causing her to react violently.
Branding places an amulet from antiquity around her neck, telling Nancy that it came from the Carpathian Mountains region and is capable of healing and destroying– and has the ability to release frightening powers.
At police headquarters, the coroner informs Lt. Dunlap that he found two puncture wounds in Nola's jugular vein and that the body was drained of blood.
A young assistant to the coroner, Mike, who shared a room in med school with “an exchange student from a small town in the Carpathian Mountains," remembers his friend's stories about vampires.
The state threatens to close the school over the unsolved murders, and consequently, Thorndyke asks Branding to take over some of her duties while she attempts to calm concerned parents.
At that moment, Glenn, Mrs.Thorndyke, and Myra break through a locked door to gain entrance into the laboratory and see that Branding's written thesis has been destroyed after being soaked with an acid.
[1] Upon its theatrical release, the United States Conference of Catholic Bishops described the film as a “Low-budget chiller...in which a new student at a girl's prep school turns into a murderous vampire after falling under the hypnotic spell of the school's feminist science teacher ... Stylized violence, hokey menace and sexual innuendo" and gave the film an “Adults Only” rating.
The film basically takes the same route as I Was a Teenage Werewolf, but never lives up to that effort, especially with Harrison’s monster turns kept to a bare minimum.
