While attending college at the University of Wisconsin in the 1960s, Carole Martinson fell in love and eloped with Phillip Vanderlin. When his parents realized she was a farmer's daughter and below them socially, they insisted they divorce.

Fast forward to 2019 and Carole is invited to a wedding cruise financed by her granddaughter's fiancé's grandfather. With no knowledge about the groom's family, Carole flies to Florida for the cruise she and her second husband never got to take. Upon her arrival, she immediately recognizes Phillip.

Phillip never forgot his first love. He is thrilled when he realizes the grandmother is the girl he was forced to leave behind so many years ago.
