When two best friends are about to fail out of high school, a visitor from the future, Rufus, provides them with a time machine to work on their senior history project. Bill and Ted travel through time picking up various historical figures and bringing them to the present to help them ace their project. Time is treated one-dimensionally. Watch for a causal loop sequence where all the boys have to do is plan to remember to hide a key in the past so they can find it now. The movie also includes a self-visitation scene where Bill and Ted convince themselves to trust Rufus.
