Nellie Hurwitz doesn’t have a first love. She has a first hate: Noah-who-may-not-be-named. And she has refused to talk about what imploded their relationship since it ended abruptly near the end of high school. For two decades, Nellie and Noah have managed to avoid seeing each other --- but the gig is up when their respective best friends, Ben and Cara, plan an intimate vow renewal at a vineyard compound in Sonoma, California. Nellie is determined to keep ancient history from ruining the trip Cara has worked so hard to plan --- but dangerously close quarters bring up feelings both Nellie and Noah have carefully locked away for years. Even amidst the eye rolls, snipes and awkwardness of their forced proximity, the two can’t shake the heady attraction they’ve always shared. Ultimately, can they find a way to move forward? Or will they backslide and blow things up for good?
