This upbeat love story features an architect named Miles who decides to modernize his life by buying a computer. Not knowing a thing about them he purchases the biggest most power system he can get ahold of, and wastes no time in having all sorts of accidents - dropping it, spilling wine on it, cross wiring it. All of which ends up causing something amazing to happen, the computer gains self-awareness! Using it's word processor, speakers and microphone the computer learns to communicate with Miles and they become friends as he teaches it about life. Then a pretty cello player moves in next door and the shy Miles and super-intelligent but inexperienced computer conspire to get her to love Miles in the best tradition of Cyrano. After the computer and the woman start to share music together through the heating ducts the computer falls for the woman too. Soon man and machine are battling for who has the right to date her. In the end the computer concludes that it doesn't have a chance with the woman and wishes the couple a happy life together. It downloads itself into the electrical system and departs for destinations unknown, but not before invading a local radio station's computers to request a musical tribute to the new couple.

Nick Pulovski (Clint Eastwood) is a cop who is presently assigned to the auto theft division and who for the most part of his career has not done anything worthwhile. When he discovers that a man named Strom (Raul Julia) is the brains behind a major car theft and chop shop ring, he sees this as his opportunity to do something. After his partner is killed, the case is then transfered to homicide, so he is taken off the case and assigned a new partner, David Ackerman (Charlie Sheen).  Pulovski, feeling that Strom is his and his alone to catch, decides to continue pursuing him but Ackerman (who tries to play by the rules) is not sure what to do.
