In Dave, Kevin Kline stars in dual roles as President Bill Mitchell and a temp agency owner named Dave Kovic. When the President has a massive stroke that leaves him in a vegetative state, his Chief of Staff, Bob Alexander (Frank Langella), convinces Dave to play the part. Whereas President Bill Mitchell was corrupt and nasty with a well-crafted political façade, Dave genuinely cares and wants to help people. This leads him to lock horns with Alexander, whose real agenda is to implicate the Vice President in a scandal and have "President Dave" nominate him the new VP just before pretending to have a second, fatal stroke. Ellen Mitchell (Sigourney Weaver) is the estranged First Lady who enjoys using her role to be of service to the needy, despite the lack of love in her marriage. She eventually catches on to the ruse and with her help, Dave is able to set things right and the two of them find romance along the way.
