After being snubbed at his advertising job, Los Angeles yuppie David Howard (Albert Brooks) convinces his wife, Linda (Julie Hagerty), to quit her job and join him on a cross-country road trip. The two liquidate their assets and leave the West Coast in a Winnebago, intent on finding themselves and discovering America. But during a stop in Las Vegas, the couple loses their savings at a roulette wheel and begins to see that their idealized notion of the American experience is terribly misguided.
