When the president of the United States has a stroke while engaging in extramarital activities, his aides avoid a scandal by finding a good-natured look-alike named Dave (Kevin Kline) to take his place. Not beholden to any special interests, Dave starts doing things that are good for the country rather than doing what is politically savvy. His approval rating goes way up, and the country loves him.
Things start to go sour, though, when the president’s aides realize he will not do their evil bidding, and the first lady (Sigourney Weaver) starts to realize that Dave is not the man she married. Dave is one of those feel good movies that makes you smile for a long time after it’s over.
