On Christmas Eve, ten strangers board a bus traveling across Texas. Far
out in the wilds they collide with a meth-addicted biker. Forced off the
road by other members of the gang, the passengers take refuge in the
hell hole of an abandoned scrap yard. They use improvised weapons and
sheer guts to mount a defense against the murderous bikers but, as their
numbers dwindle, they realize that their survival depends on doing the
unthinkable. They must go on the offensive.
