The Guilt Trip

A young man invents a new cleaning product, and embarks on a road trip across the country to pitch the product to supermarkets. He decides to take his mother along, after learning about the boyfriend she had before she married his father. Mom instead uses the opportunity to nag her son about his lack of girlfriend or wife. In the end it's your typical road trip movie, where the characters go from A to B and have assorted adventures along the way, and, in this case, a lot of talking.
