Here is what I remember. A old woman decides to take her two children (or two grandchildren ?) and move to California. They set out in their car. The old woman is getting stressed out driving, but she says “I’m a tough old merch.” Shortly after, she dies of a heart attack. Then, the daughter continues driving. I remember they got pulled over by the police. He sees the license plate and asks “Where are you headed?” Does this sound familiar?
