Wikipedia synopsis excerpt:
The film opens in the utopian future that results from the music of Bill (Alex Winter) and Ted (Keanu Reeves). Chuck De Nomolos (Joss Ackland), who detests this society, steals one of the time-traveling phone booths with the aid of two robots fashioned after Bill and Ted, and travels to the late 20th century, with the intent to prevent Bill and Ted from winning the San Dimas Battle of the Bands. Rufus (George Carlin) attempts to stop De Nomolos but becomes lost in the circuits of time.. . De Nomolos arrives and has the robots replace Bill and Ted, killing them by throwing the two over the side of a cliff at Vasquez Rocks. The robots behave rudely to the princesses and work to ruin the duo's fame. Bill and Ted's souls are met by Death (William Sadler), who challenges them in a game for their souls.
