At the beginning of the movie Miss Daisy is backing out of her garage to go to the store but loses control of the car and backs it over a wall into the neighbor's yard. Miss Daisy’s son Boolie tells her besides destroying her new car the accident means she cannot drive any more because no insurance company will insure her. He tells her she will have to get a chauffeur. She refuses, but Boolie is determined to find her one. Meanwhile she is stuck at home and is unable to run errands or visit friends.
