Over the Hill (1992)

Alma can't stand to have one more birthday without seeing her estranged daughter, Elizabeth, who lives in Sydney, Australia. But Alma doesn't fit into her daughter's political-hostess life even for a visit, and she finds more sympathy in her granddaughter. Alma, in a burst of rebellion, buys a supercharged hotrod and sets out on a voyage of self-discovery to Melbourne--if she can remember to stay on the left side of the road. Along the way, she meets con artists, gangsters, and a ponytailed white-knight in a camper and she finds not only adventure and romance, but also the courage to go back and face her relationship with her daughter and set it right.
