Americans Michael Pappas and Cathy Featherstone, a young couple from Chicago who have just graduated from college, have known each other about 10 years and have been together about half that time. They vacation for almost the entire summer on the Greek island of Santorini. Michael sees it as a chance to enjoy one last crazy summer before going to work at his recently deceased father's business in the fall. When they visit a nude beach crowded with other young tourists, they are hesitant at first but find themselves getting caught up in the uninhibited energy that surrounds them.
