Marge, the kids and Milhouse go to the library where they find there are no longer any books on the shelves. With no books for reference, the kid's reports are in danger of not being able to write their reports. Fortunately, Marge knows some history and relates to the children the following tales:
Henry VIII (Homer) tries to find a wife that will bear him a son.
Lewis and Clark (Lenny and Carl) get assistance from Sacagawea (Lisa) in their quest to explore the western territories.
Mozart (Bart) the musical child prodigy wows them in 18th century Austria, while his sister (Lisa) fights for her own musical identity.
