A man riding a deserted night train seems to be interested in the tipsy beauty sitting opposite him. He gets excited when he catches a glimpse of the sleeping woman's panties from under her skirt. When the woman wakes up, they make eye contact and it's an awkward atmosphere. She lifts her skirt to show him her panties, as if to say, "Are you excited because you saw my panties?" The two of them are alone in the empty train, with the sounds of love juices echoing and voices leaking, and the two who just met make love in an obscene night car.
