A winged being descends onto Earth in Los Angeles. He then raids a weapons warehouse and steals a police car, traveling towards the edge of the Mojave Desert. Elsewhere, a single father named Kyle stops at the Paradise Falls Diner. There, he meets the owner, Bob Hanson. Also at the diner is Bob’s son, Jeep, a short-order cook named Percy, Charlie, a pregnant waitress, Howard and Sandra Anderson, a married couple, and Audrey, their teenage daughter. Though it appears to be an ordinary day, things take a turn for the strange when the diner’s communications equipment fails and an anomalously hostile elderly woman steps inside.
