Rufus welcomes the viewer to the future of San Dimas, California in 2688, which is a utopia. He continues that 700 years ago the Great Ones ran into a problem that he had to help them out with.
The Three Most Important People in the World tell Rufus that it is time for him to help Bill S. Preston and Ted "Theodore" Logan and send him back in time in a modified telephone booth. Rufus lands in the telephone booth at the Circle K and tells Bill and Ted that he is there to help them with their history report. Another telephone booth arrives with Bill and Ted from the future. They tell current Bill and Ted to trust Rufus and to give their love to the princesses before they leave. They get into Rufus' telephone booth and he takes them to Austria in 1805. Napoleon happens to see them and orders them to be blown up, but a cannon blast hits near him and he is transported along with them when they travel in the circuits of history. Rufus takes them back to the current time and shows them the Circuits of Time Directory and then leaves in the phone booth.
Bill and Ted land back at the Circle K where they first met Rufus and gave advice to their now past selves and then travel to San Dimas in the future for their exam. Later, Bill and Ted are practicing when Ted notices that nothing has really changed in their lives. Rufus shows up with Princess Joanna and Princess Elizabeth who join the band and as Bill, Ted, Joanna and Elizabeth play, Rufus promises that in time, they do get better.
During the events of Bill & Ted's Bogus Journey (1991) played by George Carlin
In Sam Dimas, California in 2691, at Bill and Ted University, in The Physics of Acoustical Reverberation class, Rufus arrives in the time booth, which looks like a telephone booth, with Thomas Edison, Bach, Sir James Martin, and Ria Paschelle. Suddenly De Nomolos and his followers blow open the doors to the classroom and start setting up equipment. De Nomolos enters the classroom and tells Rufus his plan to destroy the system. De Nomolos then reveals his secret weapon, Evil Bill and Evil Ted who are automatons that look exactly like Bill and Ted. Evil Bill and Ted then tell the crowd their mission objectives, to kill Bill and Ted and then give a speech during the Battle of the Bands which will make certain the future will be changed. Evil Bill and Evil Ted get into the time booth and right before they go into the past, Rufus uses a guitar to hitch a ride along with them by using it like a grappling hook.
Back on Earth during the current time, Bill, Ted, Joanna, and Elizabeth are practicing their music in front of Ms. Wardrobe. Ms. Wardrobe tells them that they are terrible, but she will give them the midnight slot during the 4th Annual Battle of the Bands. Later, the first band to play is Primus. Ms. Wardrobe asks Evil Bill and Ted where Joanna and Elizabeth are, and they tell her that they are hanging from the rafters, and they are going to kill them during the finale. Ms. Wardrobe introduces the Wyld Stallyns and Evil Bill and Ted walk onstage. Bill and Ted walk onstage with the Grim Reaper and tell the crowd they are the Wyld Stallyns and Evil Ted shows them where Joanna and Elizabeth are hanging from the rafters. Good Robot Bill and Good Robot Ted walk on stage and punch the heads off of Evil Bill and Ted and then make them explode while the crowd cheers. Big Station, who has reverted to the Stations lowers Joanna and Elizabeth and they kiss Bill and Ted.
De Nomolos appears in the time booth and introduces himself to Bill and Ted. He pulls out a rifle and then shoots a projectile that takes over the broadcast satellites across the world. He tells the world that he wants them all to see the transfer of power. He continues that from now on society will be based on his ideas and not Bill and Ted’s. Bill and Ted decide to go set things up after things are resolved so a sandbag and cage fall on De Nomolos in the present. De Nomolos counters their idea and says that in the future he will set it up so a key appears, which it does. He opens up the cage and steps out and another rifle appears in his hand. When he pulls the trigger a piece of fabric comes out with the words Wyld Stallyns Rule. The Grim Reaper tells De Nomolos that his shoes are untied and when De Nomolos bends over to look, the Grim Reaper gives him a Melvin. Captain Logan arrests De Nomolos and takes him away. Ms. Wardrobe reveals herself to be Rufus in disguise and Rufus tells them about De Nomolos. The Wyld Stallyns travel in the time booth to practice and then appear seconds later, but also with a child each. They introduce the rest of the band which also now include the Stations Good Robot Bill and Good Robot Ted and the Grim Reaper. The Wyld Stallyns play and win the Battle of the Bands and eventually play on Mars.
