The media have descended on Garrett Island, a small, isolated community that is the setting of a visionary experiment. All the residents’ cars were sent to the mainland, and for the past month the islanders have been “driving” the Arrival, a revolutionary autonomous vehicle. With a simple voice command, an Arrival will take you wherever you want to go. As the excitement reaches a fever pitch, public relations executive Sandra Montrose prepares for Arrival Inc.’s flashy press event. But as the celebratory day gets underway, disaster strikes. A visiting journalist has vanished, possibly murdered. Before long, the Arrivals run amok, no longer taking orders from their passengers. They’re starting to organize. They’re beginning to hunt. And they seem hell-bent on killing any human they encounter.
