While trying to get their lives back on track after the loss of their four year old son, Bryn and Paul Shaw move to the charming old Beacon Apartments. Bryn begins seeing a ghostly little boy skulking around the building. With the help of an eccentric young professor and a tough old beat cop, Bryn tries to uncover the details of the boy's death. She hopes that freeing the child will allow him to carry a message to her son. Too late she realizes a second malevolent entity stalks the halls of the Beacon: one that doesn't want the boy to escape.

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.
