Everything was settled for 18 year old Jeffrey Willis (Matt Dillon) the plumber's son from Brooklyn: one last summer of carefree fun before college. That was until his friends came speeding up in a 1960 convertible to invite him out for an innocent day at their parents fancy beach club on Long Island. Suddenly a summer of packing groceries and lusting after stock girls becomes a season of discovery as he begins working as a cabana boy at the El Flamingo Beach Club. Here, his eyes are opened to a world of beautiful people with seemingly perfect lives as he falls in love with pretty beach girl Carla, turning his back on his family. However, it is 1963 - a summer of innocence and change - a summer of awakening.
