Soon after their journey begins, the spirited foursome are spooked by a menacing pair of bikers, Holden (Lee Tergesen) and his girlfriend, Alex (Cyia Batten). When Alex chases the group's jeep, propelling thim into a serious accident, Chrissie is thrown from the vehicle. As Alex attempts to rob the injured trio, Sheriff Hoyt (R. Lee Ermey) arrives on the scene and turns the tables on their would-be-assassin.

In an effort to save her friends, she attempts to convince Holden to help her, but he is on a one-man rampage to avenge his girlfriend's death. As Chrissie witnesses the horrors inflicted by teh Hewitt family upon the people she loves, she realizes she is their only hope of survival.
