The wife of a man named John Wick has succumbed to a terminal illness. Just before she died, she had given John a gift to help him with the grieving process: a beagle puppy named Daisy. Over the next few days, he bonds with the puppy, driving her around in his vintage 1969 Ford Mustang Mach 1. Trouble brews when at a gas station, a trio of hoodlums led by a young Russian gangster named Iosef Tarasov insists on buying his car. John assures him the car is not for sale, but Iosef refuses to take “no” for an answer. He makes his frustrations known when he and his cohorts follow John to his house, knock him unconscious, kill Daisy, and steal his car.
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.
