Returning to the future via a lightning strike that powers the machine, Marty discovers a vastly improved situation for the McFly family, as a much more confident George has become an accomplished science fiction author, Marty's two older siblings have better lives, he owns the car of his dreams, and an apparently-softened Biff is now an auto detailer, rather than George's supervisor.
