Ferdinando Baldi’s Italian erotic comedy unfolds primarily on a train, which immediately sets the stage for some awkward situations. The women in the film struggle to keep their clothes on as sexual energy builds within the confined space—it's an unusual European production that caters to base desires. The movie boasts a remarkable ensemble including Annie Belle, Anna Maria Rizzoli, Marisa Mell, Marina Hedman (Marina Frajese), and Moana Pozzi (Anna Maria Pozzi). Each actress has opportunities to disrobe; but Serena Grandi, who appears in her second film, is the one who truly captures attention. She portrays a young woman about to get married and a virgin who unexpectedly finds herself in an uncomfortable predicament with the wrong person.
