"For as long as anyone can remember, it's been Amy, Jo, and Ryan. Amy and Jo, the inseparable Sharp twins, who couldn't be more different. Amy and Ryan, the high-school sweethearts turned husband and wife, who have the next ten years planned out perfectly. Together through high school, college, weddings, there's nothing that could tear the three of them apart. While it's become harder for the group to spend as much time together, with life only getting more complicated with age, they always make it a priority to reunite every summer at the Sharp family home in Kismet on Fire Island, where they've been vacationing since they were children. But as this year's 4th of July weekend approaches, something feels off. Jo's whirlwind engagement and wedding ceremony now eclipse the twins' long-awaited 30th birthday.
