In the end of summer, strikingly beautiful and intelligent Marion who just got divorced brings her 15 year old cousin Pauline to a Normandy coastal resort for a short vacation. At the beach, they meet Pierre, an old friend who is still desperately in love with Marion, and Henri, an older hedonist who is only interested in sex and divides his time between Marion and a local candy girl, Louisette. Paulette meets a young man Sylvian but their romance does not live long thanks to Henry's cynicism and egotism. "Pauline at the Beach" is a very sexy, intelligent, and charming dramedy about love, lies, and desire and how sometimes the teenagers have a better sense of reality and better understanding of these matters than the adults around them.
