Sharon's dream trip across the USA in a Winnebago founders at the start of Route 66. After spending a few weeks in the Caribbean at Tom's luxury apartment, where she couldn't stop being sick, she's already stir crazy at being confined to an RV in a trailer park near Chicago. She's fed up, hormonal and cold. A surprise change of plan makes her much happier, although it's a bumpy ride at first. With a clutch of yellow-robed monks, another chauffeur called Mark and a couple of homeless kids, new characters open up her life and give it new meaning.
