Homer test drives an electric car because it'll get him a gift. The gift is that Homer and Marge get to be part of a test audience for the new film of Mel Gibson, a remake of Mr. Smith au sénat (1939). Everybody loves the film except for Homer, who totally hates it. Because a very insecure Mel Gibson thinks Homer is the only one who dares to speak his mind he asks Homer to help him change the film. Therefore, Mel Gibson takes Homer, Marge, Bart and Lisa to Hollywood.
