Beyond the Door III (1989)

Venturing into the heart of Yugoslavia to immerse herself in the country's profound history, the innocent American high school student, Beverly Putnic, embarks on a journey that will forever change her life. With six classmates in tow, Beverly sets her sights on a secluded village, a place where ancient pagan rituals still echo through the cobblestone streets. Guided by the enigmatic Professor Andromolek, their trip swiftly transforms from a simple academic excursion into a chilling descent into the occult. As the villagers' forbidding nature reveals itself, Beverly and her companions find themselves ensnared in a terrifying web spun by none other than the Professor himself, a devoted Satanist with a diabolical plan. Desperate to escape, they board a serendipitous train, only to discover that their nightmare has merely shifted tracks. Trapped within the steel beast, they are stalked by the ominous Prince of Darkness, his malevolent eyes set on Beverly, the virgin bride. Beverly is the key, her purity the final piece to summon Satan back into the world. The stakes could not be higher – her virginity stands between the world and its descent into eternal darkness. As the shadows close in and the train thunders towards its unknown destination, Beverly must make a choice. Can she evade the clutches of evil and alter her fate, or will she succumb to the Prince of Darkness, sealing the world's doom in the process? The clock is ticking, and every passing moment brings Satan closer to his sinister resurrection.
