The ghost of Frank Capra must have smiled when he saw Dave, an amusing and effective update of one of Capra's favorite themes – the scrupulously honest little guy who becomes a force for good against a corrupt system. Dave Kovic (Kevin Kline) runs an employment agency and seems to genuinely enjoy finding work for people who need it. He also bears a striking resemblance to the president of the United States, Bill Mitchell (also played by Kline) and occasionally gets work as a Bill Mitchell impersonator. One day, Dave gets a call from the Secret Service – for security purposes, they want to hire him to act as a decoy for an upcoming appearance by the president. All goes well, but later that evening President Mitchell suffers a massive stroke while in bed with his mistress. Wanting to keep the matter a secret, two of the president's top advisors appeal to Dave to stand in as Bill Mitchell until he regains his health.
