Plot summary

Della Myers, a suburban housewife, lives with her twin children and her abusive husband, Kenneth. On Christmas Eve, she drives to the local mall to buy gift-wrap. In the jam-packed parking lot, she notices an old car taking up two spaces and decides to leave a note on the windshield calling them out. After the mall closes, her car is blocked by the old car and she's threatened by four thugs. She escapes in her vehicle, but they drive after her. She crashes at a dead end construction site at the edge of a forest. What unfolds in the desolate woods is Della's lone fight for survival against a gang of angry young men with murderous intent.
