With what has to be my least favorite title ever for a Girls Underground example (though its alternate title, “Beyond the Door III” is somewhat better), Amok Train nonetheless was a rather interesting movie with some good imagery. Horror genre, of course, as most GU movies (that aren’t children’s animation) tend to be.
Beverly, a college student (horror heroine Girls Underground usually are a bit older than the fantasy-novel types), goes on a class trip to Serbia to see a passion play with heavy pagan undertones. Just as she leaves, unbeknownst to her, her mother is killed in a car crash (making her the typical orphan). The professor guiding the students quickly reveals himself to be her adversary (or more accurately, the primary henchman of the true adversary, who is much bigger and scarier but who we don’t see until the end). He goes after the whole group of kids (her default companions, although they don’t like her), most of whom (Beverly included) escape on a train, but all of whom begin to be picked off one by one as the film goes on.
Beverly is helped along the way by the train conductor, and eventually a mysterious piper who plays his music amidst the calamity. It is revealed that she was always the target, the purpose for the whole trip in fact – she has a birthmark which designates her as fit to be the virgin sacrifice to the devil, and now the villagers are eager to use her in their ritual. Eventually, on a runaway train with no crew or companions left, Beverly returns to the village and acquiesces to the ritual, piquing the adversary’s interest. She appears to have been won over to the dark side, but taking a page from Lily’s playbook (in Legend), it is just a ruse, and Beverly waits until the ritual climax to reveal her true intentions, and why she is no longer a fitting sacrifice, thereby ruining the devil’s plans.
