On a red-eye flight to Boston from Los Angeles, 10 people wake up to a shock: All of the other passengers and crew have vanished. When they try to contact the ground they make no connections. They land the plane only to discover that things haven't changed, but it's like the world is dead. Nobody's there, the air is still, sound doesn't echo, the food is tasteless, and a distant sound comes closer and closer. A race of monstrous beings bent on their destruction is heading for them, eating everything in sight.
