Four 16-year-old girls spend their first summer apart from each other, but stay in contact sharing their troubles, experiences, etc. Lena visits her grandparents in Greece and meets Kostos, Tibby stays at home, makes a movie, and befriends a young girl named Bailey, Bridget goes to soccer camp in Mexico and gets a crush on one of the coaches, and Carmen visits her dad in South Carolina and discovers a shocking secret. Chick flick stuff, if somewhat American in its cultural context.
