But while the family is on vacation in Nantucket, Margot finds an opportunity to potentially regain her romantic love for her husband - in the form of Hadley Axelram, his ex-girlfriend. She is counting on jealousy as a relationship defibrillator. But after forcing her surfing-god husband to make plans for a surfing lesson with Hadley and her son, Margot is left to reminisce about the summer she fell in love with Drum, and the unexpected blossoming of their relationship. When she sees Drum and Hadley spending time together, will the spark reignite - and will her marriage be saved? Or will she find that love is truly gone from this relationship?
