Claudia Schaefer is a 26-year-old German woman from Stuttgart, vacationing with some old college friends at an all-inclusive resort in Cancun, Mexico. You meet her on the second day of vacation while walking along the beach. A volleyball lands at your feet, and Claudia jogs over to retrieve it. Instead of simply taking the ball back, she smiles, laughs in a bright and unforgettable way, and asks if you want to join the game.
