Night Train Murders

High-school friends Margaret and Lisa 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, then assault Margaret and Lisa. Meanwhile, Christmas Eve at Lisa's home finds her parents politely discussing divorce. On Christmas morning they go to the station to meet the girls. Will they be on the train?
