A single car travels along a lonely mountain road in the mountains of northern Arizona, its headlights cutting through the thick shadows of the forest around them. Within the car are Jesse and Selene, two young lovers escaping the uncertainty of their impending graduation for a night in an effort to reconcile their struggling relationship. Their romantic evening together becomes a harrowing nightmare as they are pursued off the main highway and onto a remote trail by a truck that bears down on them even as Jesse attempts to outrun it. Just as they are about to be overtaken by the vehicle, red emergency lights are lit up from its roof, revealing that they have just attempted to escape a State Trooper. Jesse pulls over, but the police vehicle continues past them on the road at breakneck speed, disappearing around a bend up ahead.
