Best friends Carly, Daniella, Lainie, and Penny – aka the self-proclaimed #SummerSisters – have been coming to the New Jersey shore town of Ocean Park Heights ever since they could remember. And every year, the girls make a bucket list and dedicate their entire summer to completing every item on it, documenting their wacky escapades on FotoSlam for everyone to see. It’s their tradition, and as long as the Summer Sisters had each other, the rocky jetty on the shore, and their bucket list, that would never change. But then, tragedy strikes after Carly – the mastermind behind the bucket list– unexpectedly passes away. As the remaining Summer Sisters try to wrap their heads around their best friend’s death, life seems determined to throw more curveballs at the girls, threatening to split the Summer Sisters up for good.
