Life is as twisty as any mountain road. No one knows this better than John, a widower, and Carrie, a new widow. One such life curve gives them a second chance at love as they cross the U.S in John's 18 Wheeler. First John saves Carrie from certain death on the Salt Flats of Utah, then he changes her life totally by taking her across the country with him on his rig. Not only does Carrie discover she can become a his 'broker' and can help John, she realizes she has a chance for true love, something she never had for 22 years with Frank. Guilt coats John like dirty oil. He's never been unfaithful to his dead wife - ever - and now this "seat cover" is bringing back feelings he hasn't felt since Janis died. Jealousy, attraction, frustration, and fury become their constant companion from the East coast to West coast as both deal with children, forgotten feelings, as life, once again, shifts their gears.
