One night of fun took a tragic turn and completely changed the lives of five teenagers forever. A year later their mistake comes back to haunt them and the consequences are a lot deadlier and darker than they imagined.
What was meant to be a night of celebration turns into a blood-soaked nightmare aboard a moving train. Years after a cruel prank shattered a young man's mind, a masked killer lurks among the partygoers, blending in, watching, waiting. One by one, they fall, victims of a vengeance years in the making. As the bodies pile up, Alana and her friends realize the truth too late-there's no escape at 70 miles per hour.
