Before: It was the perfect summer of first kisses, skinny-dipping, and bonfires by the lake. Joy, Tali, Luce, and Zoe knew their final summer at Camp Okahatchee would come to an end, but they swore they'd stay friends. After: Now, two years later, their bond has faded along with those memories. Then: That is, until the fateful flash of a photo booth camera transports the four of them back in time, to the summer they were fifteen -- the summer everything changed. Now: The girls must recreate the past in order to return to the present. As they live through their second-chance summer, the mystery behind their lost friendship unravels, and a dark secret threatens to tear the girls apart all over again.
