In this dark tale from Italian cult horror director Aldo Lado, vacationing friends Margaret (Irene Miracle) and Lisa are forced to change trains due to a bomb threat. But their second train is just as dangerous: They get stuck in a section with coldhearted thugs Blacky (Flavio Bucci) and Curly (Gianfranco de Grassi), who begin to terrorize the girls. Can Margaret and Lisa fend off the killers until their train reaches its destination?
