All Summer Long follows one charming New York couple - glamorous interior designer Olivia Ritchie and her husband Nicholas, a true southern gentleman from Charleston - as they are swept up into the world of the ultra-rich and travel the globe with a cast of zany eccentrics over one tumultuous, hot summer, and find themselves pondering the next step of their lives. This is a story of how plans evolve and lives change in unexpected ways, how even those who have everything are looking for something more to fulfill them and even the most successful can often struggle to get things together. It asks the ultimate question: can money buy happiness? From Sullivans Island to Necker Island to the beaches of Southern Spain, we'll come to recognize the face of true love, the kind that deepens and endures but only because one woman makes a tremendous leap of faith. And that leap changes them all.
