For as long as anyone can remember, it has been Amy, Jo, and Ben. Amy and Jo, the inseparable Sharp twins who couldn’t be more different; and Ben, Amy’s childhood sweetheart turned husband. But as this year’s Fourth of July weekend approaches, something feels off. Jo’s whirlwind engagement and wedding ceremony now eclipses the twins’ long-awaited thirtieth birthday. Recent arguments between Amy and Ben have left their marriage feeling more like make-believe than ever-after. And as the family beach town transforms for Jo’s wedding weekend, Amy’s trusted trio will be tested by the most unexpected hurdle yet: the arrival of a handsome, mysterious newcomer in a best man suit. One with a strikingly familiar face. A face that Amy had planned to never see again. This holiday weekend, even the strongest SPF won’t protect the Sharp twins from all the secrets about to take center stage.
