en Altadefinizione. What starts as a night of celebration for three friends quickly becomes the ultimate test of survival when their car breaks down on a frozen and deserted mountain road. The mystery grows further when they are joined by a local deputy sheriff and are stalked down the mountain by the ominous, probing headlights of a black Cadillac. It's a terrifying race - man against machine ... and Mother Nature's most fearsome elements. Based on writer / director John Murlowski's own terrifying experience on a late-night road trip in January 1983.
