The courier must go on an adventure to the magical city of New Vegas to consult The Great Mr. House and retrieve her Dazzling Platinum Chip from Benny, the Wicked Bitch of The Tops.
So she follows the Long 15 and gains some companions along the way. A dog, Rex, Boone, a man with no brain, Vulpes Inculta, a man with no heart, and Arcade, a man with no courage. They are helped along the way by Yes Man, the Good Robot of New Vegas.
If you think about it there are hundreds of parallels you can make between New Vegas and The Wizard of Oz. Heck, Victor even says something about the courier being Dorothy and him being the Tin Man.
