Julie is going on a summer holiday to France with her family. They will stay in a hotel near the small town of Moliets, which is located in a forest next to a lake. Julie's sister will swim and play games at the hotel, while her parents plan to go cycling and sailing. Julie and her brother want to go swimming and surfing at the nearby beach. One of Julie's friends from school will also be staying in Moliets and plans to meet up with Julie in the evenings.
