When Lisa struggles to find excitement and intrigue in her family heritage for a school presentation, she decides to take creative license in crafting her heritage as a Native American, since it's only for a school project. What begins as an innocent embellishment quickly turns into a web of lies when Lisa is chosen to represent the school, and 'her people,' at City Hall, and then as a keynote speaker for the National Native American Tribal Council. As a reward for his heroic act, Bart is granted a driver's license, and in an attempt to escape endless family errands and chauffeuring he flees to a faraway town where he is romanced by an older teenage girl whose expectations may prove to be too much for Bart.
