Two years ago, their exes got together immediately following their divorces, and somehow, Thea and Alex found themselves spinning a spite-fueled story about being old friends and first loves. Two years later, what began as a ruse has grown into real friendship—just friendship, despite what friends and family seem to think. But when their exes invite them on a two-week, “two family” beach vacation—daughter and dog included—Alex and Thea start to wonder if this story they’ve spun might have gotten away from them, and if it’s led them to the last place they ever thought it could: a happy ending.
