Margaret and Lisa, high school friends, take the night train from Germany to Verona to spend Christmas with Lisa's family. They flirt mildly with male passengers, including two randy delinquents in their 20s, Blackie and Curly. The four of them end up in a first-class cabin with a well-dressed woman of about 30 who has pornographic photographs in her valise. Egged on by the woman, the thugs and a male visitor to the cabin menace and then assault Margaret and Lisa. Meanwhile, we also see Christmas Eve and morning scenes at Lisa's home, where her parents are polite to each other while discussing divorce. On Christmas morning, they go to the station to meet the girls. Will they be on the train?
