Thirty years have passed since Christine and her father, Heinz, vacationed together. It was such a disaster - an exasperated Heinz left the moody teenager at a gas station to teach her a lesson - that Christine vowed never to travel with him again. But now her mother is insisting that Christine and her best friend, Dorothea, take Heinz along on what is supposed to be a relaxing girls’ trip to the beach. And she’s not taking no for an answer. Suddenly Christine and Dorothea have a chaperone, though high school is long since over.

From commandeering a friend’s business renovation to joining the islanders’ hunt for an escaped con artist to sabotaging his daughter’s budding romance with a handsome stranger, Heinz’s “father knows best” routine quickly wears thin. But when an unexpected turn of events shows him in a different light, Christine realizes she may not be too grown up to need her father after all.
