Their senior year is winding down and the kids from Laguna Beach are just getting started for their summer of fun...and drama. Lo, LC, Morgan and Christina are the most popular senior girls in school. The four get together one gorgeous afternoon to discuss how they can begin their last summer together. They decide on a fashion-themed formal at the luxurious Surf and Sand Hotel and they call it "A Black and White Affair." Now it's time to figure out who should be on their guest list, and of course, who should not.
