The music of Bill and Ted's band, Wyld Stallyns, has created a utopian future society. Chuck De Nomolos, who detests this society, steals one of the time-traveling phone booths and sends two robots modeled after Bill and Ted back to the late 20th century to prevent Bill and Ted from winning the San Dimas, California Battle of the Bands. Rufus attempts to stop De Nomolos but seemingly becomes lost in the circuits of time.
