A man, a robot and a dog form an unlikely family at the center of a powerful and touching adventure. Finch, a robotics engineer, wants to make sure that someone will look after his faithful companion after he dies. A rare survivor of a cataclysmic solar event that turned the world into a desert, Finch has been living in an underground bunker for years, where he has built his own world, which he shares with his dog Goodyear. He creates a robot to watch over Goodyear when he is no longer able. As the trio embarks on a perilous journey through a desolate American West, Finch strives to show his creation, who calls himself Jeff, the joy and wonder of life. Their adventure is one of both obstacles and humor, for while it is difficult for Finch to get Jeff and Goodyear to get along, he must also face the dangers of the new world.
