It was supposed to be a normal family vacation. Amanda, Clay and the kids planned the perfect vacation in the middle of nowhere on Long Island. Bustling New York was left behind, and a luxurious rental house in this heavenly place promised peace. Then one day there was a knock on Amanda and Clay\'s door. An unfamiliar couple stood at the door. Panic-stricken, they said that there was a blackout in the city, that phones and the Internet were not working. But should Amanda and Clay trust this couple? What happened in New York? Is a house isolated from civilization really a safe place for them? And are they safe from each other? What, how is this an illusion?
