While studying abroad in Romania, high school students Charley and "Evil" Ed discover that their alluring professor, Gerri Dandridge, harbors a dark secret. Fascinated by her beauty and sophistication, they are initially unaware that she is actually a real-life vampire, preying on the innocent. Charley, still coming to terms with his past encounters with vampires, tries to dismiss his suspicions, but a series of unsettling events forces him to reconsider. The revelation of Gerri's true nature thrusts the friends into a world of supernatural danger, invoking a desperate need for survival.

In an effort to save themselves and their peers from becoming victims of Gerri's insatiable thirst, Charley and Ed seek out Peter Vincent, a famous vampire hunter and television show host, whose expertise in the occult presents their only chance of survival. As they delve deeper into the vampire underworld, they uncover Gerri's sinister plans that extend beyond mere survival, threatening the lives of thousands. The trio's fight against time and the supernatural elements pushes their courage and friendship to the limits, as they strive to thwart Gerri's malevolent scheme before it's too late.
