Christmas Eve. Ten strangers are on a bus traveling through Texas. They are forced off the road by members of a motorcycle gang when they collide with one of their meth-addicted bikers. The passengers have to take refuge in an abandoned scrap yard. When their defense against the gang weakens and their numbers begin to dwindle, they must do the unthinkable and go on the offense. They use improvised weapons and sheer guts to mount a strike on the bikers.
