Val Com 17485 (Andy Kaufman), a robot designed to be a valet with a specialty in lumber commodities, meets Aqua Com 89045 (Bernadette Peters), a hostess companion robot whose primary function is to assist at poolside parties. At a factory awaiting repairs, they fall in love and decide to escape, stealing a van from the company to do so.
They embark on a quest to find a place to live, as well as satisfy their more immediate need for a fresh electrical supply. They assemble a small robot, Phil, built out of spare parts, whom they treat as their child, and are joined by Catskill, a mechanical standup comic (which is seen sitting the entire film).
A malfunctioning law-enforcement robot, the Crimebuster, overhears the orders of the repair workers to get the robots back and goes after the fugitives. With the help of humans who run a junkyard, and using Catskill’s battery pack, the robots are able to save Phil before running out of power and being returned to the factory. Brought back to the factory the robots are repeatedly repaired and their memories cleared. Because they continue to malfunction they are junked. They are found by the humans who run the junk yard and reassembled. In the junkyard they live happily and build a robot daughter. The film ends with Crimebuster, after only pretending to have his mind erased, continuing to malfunction, going on another mission to recover the fugitive robots.
